KerfSmart is a carpentry calculator built the way you measure: in feet, inches and fractions. Add up a run of trim, lay out a sheet of plywood, or figure where to clamp your straightedge, all without converting to decimals. TAPE-MEASURE CALCULATOR • Type 5' 3 1/2" + 2' 7 3/8" and get 7' 10 7/8". No decimal math. • Add, subtract, multiply and divide lengths. Length × length gives square feet; three lengths give board feet or cubic feet. • Results round to the precision you choose, from 1/2" down to 1/64", with a + or − marker when the true value is a hair over or under. • Tap any result for conversions: decimal inches and feet, millimeters, meters, square feet, 4×8 sheets, board feet and cubic yards. • Ans and a 50-entry history let you keep working from your last answer. • Full metric mode. CUT LISTS WITH THE KERF BUILT IN • Length: enter your parts and stock length. KerfSmart packs them onto the fewest boards, subtracts a saw kerf for every cut, and draws each board to scale with mark positions and the offcut. • Lumber: enter length, width and quantity. KerfSmart picks which boards to buy with the least waste, using only the widths and lengths you can get or haul home. It can also suggest a rough-sawn blank to mill. • Plywood: lays out your parts on the fewest sheets using straight-through cuts you can make with a circular, track or table saw. Each sheet is drawn to scale with numbered cut lines and step-by-step instructions like "Rip a 23 1/4" strip off the 96" × 48" panel." Lock grain direction when it matters. • Print the plan or share it as a PDF to take to the shop or the lumberyard. CIRCULAR SAW GUIDE Enter the distance to your cut line and KerfSmart tells you exactly where to clamp your straightedge, accounting for your saw's base plate offset and which side of the line is waste. Measure your saw once and never cut a piece short again. CARPENTRY TOOLS • Board feet and lumber cost, with hardwood thickness shortcuts • Even spacing for balusters, pickets and shelves, by count or by maximum gap • Stairs: risers, treads, total run, stringer length and angle, with riser and tread checks • Rafters and roof pitch: rafter and tail length, rise, run, plumb cut angle, pitch to degrees • Stud layout marks at 12", 16", 19.2" and 24" on center • Diagonal and square check, with how far out of square you are • Frame miter angles for any number of sides • Arc radius from width and rise MADE FOR THE SHOP • Set your blade kerf, saw offsets, default stock length, stair limits and fraction precision once. • Every length field accepts whatever you type: 3/32, 2.4mm, 1 1/2", 8'. • Clean light blue design with full dark mode, on iPhone and iPad. • No account, no ads, no tracking.
