Quick Answers
Fast, direct answers to the exact questions people type into a search bar mid-project — "how much does a 2x4 weigh," "miter angle for a 5 sided box," "what does 5/4 mean." Each page leads with the computed number, states the real inputs and assumptions behind it, and links to the full interactive calculator for anyone whose project doesn't match the stated example exactly. Every figure here is computed by this site's own tools, not typed from memory — see the method line on each page for exactly how.
These are deliberately short: a real answer, a real caveat, and a link to go deeper — not padded into an essay. For the fuller explanation behind any of these numbers (why the formula works the way it does, or the full method across every case), each page links back to its companion reference or explainer page rather than repeating that explanation itself.
Why this exists as a separate layer from the tools and the reference pages
A calculator answers a question once you've already opened it and typed in your own numbers; a reference page explains a system in full. Neither is the right shape for someone who already knows exactly which number they need and just wants it fast — "how many board feet in an 8/4 board 6 inches wide and 8 feet long" isn't a request for the quarter system explained, it's a request for one number, with enough of the method shown to trust it. That's the gap this layer fills: single-question, single-answer pages built around one specific, commonly searched case rather than the general method behind it.
How to tell an answer page from an explainer or reference page
If a question has one specific case in mind — a named size, a named species, a named side count — it's an answer page here. If the same question is really asking for the whole system behind that case, the deeper page it links to is the better stop: miter angles for common polygons has the full table this section's individual angle answers are drawn from, and how to calculate lumber cost per board foot covers the general method behind the individual cost answers below. Landing on the wrong one first is not a real problem either direction — every answer page links to its deeper companion, and every deeper page exists independently of any single answer instance.
How Much Does a 1x4 Weigh
Truck-bed payload math is the real reason anyone looks up a 1x4's weight — a single 8-foot board runs under four pounds, but a bundle of twenty adds up fast.
How Much Does a 1x6 Weigh
A 1x6 weighs 6.19 lb over 8 feet — exactly the extra 2 inches of width scaled linearly onto the 1x4's 3.94 lb at the identical board thickness of 0.75 inches.
How Much Does a 1x8 Weigh
An 8-foot 1x8 weighs 8.16 lb, right about where a stack of them starts feeling like real weight rather than something you'd casually toss over a shoulder.
How Much Does a 1x12 Weigh
A 1x12 weighs 12.66 lb over 8 feet — nearly as much as a 2x6 despite being less than half as thick, purely because it's almost 6 inches wider than the 2x6.
How Much Does a 2x4 Weigh
7.88 lb is the benchmark figure for an 8-foot SPF 2x4 — the single size people check most, usually while sizing a truck load or a shipping quote first.
How Much Does a 2x6 Weigh
A 2x6 comes in at 12.38 lb over 8 feet, about 57% heavier than a 2x4 at the same length, tracking almost exactly the jump in actual board width alone.
How Much Does a 2x8 Weigh
16.31 lb for an 8-foot 2x8 puts it solidly in two-hands-required territory, mostly because a long, floppy board is hard to control solo at that weight.
How Much Does a 2x10 Weigh
20.81 lb is close to where an 8-foot board stops being a comfortable carry, especially once it's a header being lifted overhead rather than walked flat.
How Much Does a 2x12 Weigh
25.31 lb makes an 8-foot 2x12 the heaviest board in the common dimensional lineup — though at that length, leverage costs more than the raw weight does.
How Much Does a 4x4 Post Weigh
An 8-foot 4x4 post weighs 18.37 lb, noticeably more than a 2x8 of the same length, because a square 3.5-inch cross-section holds more volume than it looks like.
How Much Does A Walnut 2x4 Weigh
A walnut 2x4 weighs 11.08 lb over 8 feet, about 41% heavier than the equivalent SPF framing 2x4, purely because walnut's density runs well above softwood's.
How Much Does A White Oak 2x4 Weigh
At 13.71 lb, a white-oak 2x4 is the heaviest species this site compares at that cross-section — a direct result of the tyloses that seal its pores shut.
How Much Does A Cherry 2x4 Weigh
Black cherry at 2x4 dimensions weighs 10.21 lb over 8 feet, lighter than most hardwoods compared at that cross-section thanks to cherry's moderate density.
How Much Does A Hard Maple 2x4 Weigh
A hard-maple 2x4 weighs 12.83 lb over 8 feet, the second-heaviest species compared here at that size — dense enough to explain its butcher-block reputation.
How Much Does A Red Oak 2x4 Weigh
Red oak at 2x4 dimensions weighs 12.78 lb over 8 feet, within a rounding error of hard maple's 12.83 lb despite the two sharing almost nothing structurally.
How Much Does A Douglas Fir 2x4 Weigh
A Douglas-fir 2x4 weighs 9.33 lb over 8 feet, about 18% heavier than the generic SPF default at the identical size, since its own density beats SPF's blend.
How Much Does A Southern Yellow Pine 2x4 Weigh
Southern yellow pine at 2x4 dimensions weighs 10.21 lb dry, but most SYP at the yard ships pressure-treated and genuinely wet, so real boards often run heavier.
How Much Does A Teak 2x4 Weigh
A teak 2x4 weighs 11.93 lb over 8 feet, though at teak's roughly $45-per-board-foot price, weight is rarely the number that actually matters most here.
How Much Does A Sheet Of 3 4 Plywood Weigh
A full 4x8 sheet of 3/4 inch plywood weighs 65.19 lb — heavy enough that carrying it alone up a flight of stairs is a genuine two-person job for most people.
How Much Does A Sheet Of 1 2 Plywood Weigh
A 1/2 inch plywood sheet weighs 42.52 lb, light enough for one person to manage alone, unlike the 3/4 inch sheet a size up that generally needs two people.
How Many Board Feet In a 2x4x8
An 8-foot 2x4 contains 3.5 board feet, not the 5.333 a naive 2-by-4-by-8 calculation gives — that naive figure uses the nominal size instead of the actual one.
How Many Board Feet In a 2x4x10
A 10-foot 2x4 contains 4.375 board feet, exactly 1.25 times the 3.5 board feet an 8-foot length of the same cross-section holds, since length scales linearly.
How Many Board Feet In a 2x6x8
An 8-foot 2x6 contains 5.5 board feet — at this length and thickness, the board-foot count happens to equal the board's actual width in inches exactly.
How Many Board Feet In a 2x6x10
A 10-foot 2x6 contains 6.875 board feet, 1.25 times the 5.5 board feet an 8-foot length of the same cross-section gives, a ratio every matched pair here shares.
How Many Board Feet In a 2x8x10
A 10-foot 2x8 contains 9.063 board feet, or nine and a sixteenth — the fraction survives because 7.25 inches doesn't divide as cleanly at 10 feet as at 8.
How Many Board Feet In a 2x10x10
A 10-foot 2x10 contains 11.563 board feet, heavy enough in a header or beam application that a matched set is worth totaling carefully rather than estimating.
How Many Board Feet In a 2x12x12
A 12-foot 2x12 contains 16.875 board feet, the largest single figure among the dimensional sizes this site tracks, from both the widest width and a long length.
How Many Board Feet In a 1x6x8
An 8-foot 1x6 contains 2.75 board feet — at this thickness and length, board feet always works out to exactly half the board's own actual width in inches.
How Many Board Feet In a 1x8x8
An 8-foot 1x8 contains 3.625 board feet, following the half-the-actual-width pattern every 1x board at this length shows, sitting between the 1x6 and the 1x10.
How Many Board Feet In a 1x10x8
An 8-foot 1x10 contains 4.625 board feet, half its actual 9.25 inch width — a full board foot more than the 1x8 gives at that identical length and thickness.
How Many Board Feet In a 1x12x8
An 8-foot 1x12 contains 5.625 board feet, the highest count in the 1x-at-8-foot family, still following the same half-actual-width pattern the group shows.
How Many Board Feet In a 4x4x8
An 8-foot 4x4 post contains 8.167 board feet, nearly identical to a 2x12x8's total despite looking smaller, because a square cross-section hides real volume.
How Many Board Feet In a 6x6x8
An 8-foot 6x6 timber contains 20.167 board feet, the largest total among every size-and-length combination this site's pages cover, purely from cross-section.
How Many Board Feet In a 4 4 Board 8 Inches Wide 10 Feet Long
A rough 4/4 board, 8 inches wide and 10 feet long, contains 6.667 board feet, computed at the full 1 inch rough thickness before any surfacing touches it.
How Many Board Feet In An 8 4 Board 6 Inches Wide 8 Feet Long
A rough 8/4 board, 6 inches wide and 8 feet long, contains exactly 8 board feet — a clean number from these specific dimensions, not a general 8/4 rule.
How Much Does 100 Board Feet Of Walnut Cost
100 board feet of black walnut runs about $1,400 at a typical 2026 rate of $14 per board foot — premium pricing from scarcity, not difficulty milling it.
How Much Does 100 Board Feet Of White Oak Cost
100 board feet of white oak runs about $900 at a typical 2026 retail rate of $9 per board foot, well under half of what the same volume of walnut costs.
How Many Board Feet In A Cord Of Wood
A cord of wood contains 1,536 board feet by pure unit definition — 128 cubic feet per cord times 12 board feet per cubic foot — not a yard invoice figure.
How Many Board Feet In A Standard 4x8 Sheet Of 3 4 Plywood
Treated as one large board, a standard 4x8 sheet of 3/4 inch plywood contains 24 board feet, a conversion that exists to compare it against solid lumber cost.
Miter Angle For a 3 Sided Box
A 3-sided box needs a 60 degree miter at each end — the steepest cut in the common flat-frame set, and the one where a small setup error costs the most.
Miter Angle For a 4 Sided Box
45 degrees is the one flat-frame setting every miter saw already has a detent for, which is exactly why the odd side counts nearby catch people off guard.
Miter Angle For a 5 Sided Box
A regular 5-sided box needs a 36 degree miter, not the 40 or 45 a quick mental guess tends to land on — the most commonly mis-guessed angle in this set.
Miter Angle For a 6 Sided Box
30 degrees is the miter angle for a regular hexagon — a common bandsaw-box size, and the same per-edge setting a 12-segment turning ring also happens to use.
Miter Angle For a 7 Sided Box
A 7-sided box needs a 25.71 degree miter, and unlike its neighbours the true value never resolves cleanly, since 180 divided by 7 is a repeating decimal.
Miter Angle For a 8 Sided Box
22.5 degrees cuts a regular octagon, and it's the largest side count in the common set most compound miter saws still carry a built-in stop detent for.
Miter Angle For a 9 Sided Box
A 9-sided box needs a clean 20 degree miter, oddly the least-detented angle in this whole family even though it's a rounder number than the octagon's 22.5.
Miter Angle For a 10 Sided Box
18 degrees cuts a regular decagon — exactly half the pentagon's 36 degree angle, since a decagon's ten corners are twice as many steps around the same circle.
Miter Angle For a 11 Sided Box
An 11-sided box needs a 16.36 degree miter, and like the 7-sided case the true value repeats forever — though eleven sides rarely shows up in real furniture.
Miter Angle For a 12 Sided Box
15 degrees cuts a regular dodecagon — the finest division in the common polygon set, and the default angle behind a 12-segment turning ring on the lathe.
Compound Miter Angle For a 4 Sided Planter 15 Degree Slope
A 4-sided planter sloped 15 degrees needs a 44.01 degree miter and a 10.55 degree bevel — the gentlest of the four compound planter examples this site covers.
Compound Miter Angle For a 6 Sided Planter 15 Degree Slope
A 6-sided planter sloped 15 degrees needs a 29.15 degree miter and a 7.44 degree bevel — the shape sold in most garden-centre hexagon planter kits today.
Compound Miter Angle For a 8 Sided Planter 10 Degree Slope
An 8-sided planter sloped only 10 degrees needs a 22.19 degree miter and a 3.81 degree bevel — the shallowest slope paired with the largest side count.
Compound Miter Angle For a 5 Sided Planter 20 Degree Slope
A 5-sided planter sloped 20 degrees needs a 34.32 degree miter and an 11.6 degree bevel, the steepest slope and largest bevel of any planter combination here.
Compound Miter Angle For Crown Molding 38 Degree Spring Angle
Crown molding with a 38 degree spring angle at a square corner needs a 31.62 degree miter and a 33.86 degree bevel — the traditional colonial-profile setting.
Compound Miter Angle For Crown Molding 45 Degree Spring Angle
Crown molding with a 45 degree spring angle needs a 35.26 degree miter and an exact 30 degree bevel — a rare compound setting that lands on a saw's own detent.
Segmented Turning Angle For An 8 Segment Ring
Each segment in an 8-segment turning ring gets cut at 22.5 degrees, the same flat-frame angle an octagon uses, applied instead to staves glued into a circle.
Segmented Turning Angle For a 12 Segment Ring
Each segment in a 12-segment ring gets cut at 15 degrees, the default count most segmented-turning books teach first, before anyone customizes the stave count.
Segmented Turning Angle For a 16 Segment Ring
Each segment in a 16-segment ring gets cut at 11.25 degrees, the tightest of the three counts here, where accumulated error becomes a real gluing problem.
How Much Will a 12 Inch White Oak Panel Move
A 12 inch white oak panel grows about 0.252 inches across its width over a real seasonal swing — the widest movement of any domestic species this site covers.
How Much Will a 24 Inch White Oak Panel Move
A 24 inch white oak panel grows about 0.504 inches across its width over the same swing — exactly double the 12 inch figure, since movement scales with width.
How Much Will a 12 Inch Walnut Panel Move
A 12 inch black walnut panel grows about 0.187 inches across its width over a real seasonal swing — noticeably less than oak or maple at the same width.
How Much Will a 12 Inch Cherry Panel Move
A 12 inch black cherry panel grows about 0.17 inches wide across a year's humidity swing — modest, though cherry's real reputation issue is color, not swelling.
How Much Will a 12 Inch Hard Maple Panel Move
Seasonal humidity moves a 12 inch hard maple panel's width about 0.238 inches — the second-highest movement figure this site tracks, behind only white oak.
How Much Will a 12 Inch Yellow Poplar Panel Move
A 12 inch yellow poplar panel widens about 0.197 inches as shop humidity swings, an unremarkable mid-table figure that fits how poplar actually gets used.
How Much Will a 12 Inch Red Oak Panel Move
A 12 inch red oak panel widens about 0.206 inches through a normal humidity swing, noticeably less than white oak despite the two species sharing one genus.
How Much Will a 12 Inch Teak Panel Move
Teak barely moves — a 12 inch panel widens only about 0.139 inches season to season, one of the smallest figures here, and a reason it stands on boat decks.
How Much Will a 12 Inch Honduran Mahogany Panel Move
Movement rarely gets lower than mahogany's: a 12 inch panel widens only about 0.098 inches winter to summer — the smallest figure this movement family covers.
How Much Will a 12 Inch Sapele Panel Move
A 12 inch sapele panel widens about 0.178 inches across a typical humidity year, nearly double the mahogany figure it's routinely sold as a substitute for.
How Much Will A Quartersawn White Oak Panel Move
A 12 inch quartersawn white oak panel grows about 0.134 inches across its width — a little over half of what the same width moves cut flat-sawn instead.
How Much Gap Should I Leave For A Breadboard End
Leave roughly 0.504 inches of working clearance for a breadboard end on a 24 inch white oak tabletop — the full seasonal swing the joint absorbs at one point.
How Much Gap Should I Leave For A Tabletop In A Frame
A 24 inch black walnut tabletop captured in a frame needs roughly 0.374 inches of clearance across its width to move freely without the frame restraining it.
How Much Will a 6 Inch White Oak Board Move
A 6 inch white oak board still widens about 0.126 inches as the seasons turn — an eighth of an inch, easy to dismiss until it's a single face-frame stile.
How Much Will a 36 Inch Glued Up Walnut Panel Move
A 36 inch glued-up black walnut panel grows about 0.562 inches across its width in service — over half an inch on a panel most makers build from several boards.
How Much Will A Butcher Block Countertop Move
A 25 inch edge-grain hard maple butcher block grows about 0.24 inches across its depth in service, using the stable radial face rather than a flat-sawn one.
How Much Will Plywood Move With Humidity
Plywood moves roughly a tenth of what solid wood of a comparable species moves in-plane, because its cross-laminated plies restrain each other's own movement.
What Does 4 4 Mean
4/4, or four-quarter, means 1 inch of rough thickness before any surfacing at all — the baseline the entire hardwood quarter grading system is built from.
What Does 5 4 Mean
5/4, or five-quarter, means 1.25 inches of rough thickness — a quarter inch thicker than 4/4, and the size decking and shelving stock is commonly sold at.
What Does 6 4 Mean
6/4, or six-quarter, means 1.5 inches of rough thickness, half again the 4/4 baseline, and the size most reached for when table legs need real substance.
What Does 8 4 Mean
8/4, or eight-quarter, means 2 inches of rough thickness — double the 4/4 baseline, the go-to size for turning blanks and heavy furniture parts needing bulk.
What Does S4s Mean
S4S means surfaced on all four sides — planed smooth on both faces and jointed square on both edges, which is why a 2x4 measures smaller than its name promises.
What Does S2s Mean
S2S means surfaced on two sides — a board planed smooth on its wide faces with the edges left rough for the buyer to rip and true up themselves later.
How Many Quarters Is a 2 Inch Board
A 2 inch rough board is 8/4 — quarters are just the rough thickness in inches multiplied by four, converting cleanly with no rounding involved at all.
How Many Board Feet In A Cubic Foot
One cubic foot equals exactly 12 board feet, since a cubic foot is 1,728 cubic inches and a board foot is defined as exactly 144 cubic inches, no rounding.
How Much Does A Board Foot Cost
A board foot runs anywhere from about $3 to $250 or more, depending almost entirely on species — construction softwood at the low end, exotics at the top.
How Many Linear Feet In 100 Board Feet Of 2x6
100 board feet of 2x6 works out to about 145.5 linear feet, since a single 2x6 at its actual 1.5 by 5.5 inch size yields only 0.6875 board feet per foot.
What Size Pilot Hole For a 6 Screw
A #6 wood screw wants a 0.0781 inch pilot hole in softwood or 0.0938 inches in hardwood — 5/64 and 3/32 on a common fractional drill-bit sizing index.
What Size Pilot Hole For a 8 Screw
The softwood-to-hardwood pilot gap holds at exactly 1/64 inch across every gauge this site covers — for a #8 screw that's 0.0938 inches against 0.1094.
What Size Pilot Hole For a 10 Screw
A #10 wood screw wants a 0.1094 inch pilot hole in softwood or 0.125 inches in hardwood — reached for once a joint has to resist real pull-out force under load.
What Size Pilot Hole For a 12 Screw
#12 is the heaviest common wood-screw gauge before builders switch to structural screws — its pilot hole runs 0.125 inches in softwood, 0.1406 in hardwood.
What Length Pocket Screw For 1 2 Material
1/2 inch material takes a 1 inch pocket-hole screw, the shortest standard length in the range, sized for thin plywood cabinet backs and drawer bottoms.
What Length Pocket Screw For 3 4 Material
3/4 inch material takes a 1.25 inch pocket-hole screw, the length behind most pocket-hole joinery since 3/4 inch is cabinet-grade work's default thickness.
