Walls & Ceilings
Drywall quantity and cost, compound, paint, and pattern-aware wallpaper.
04Drywall mudEstimate drywall joint compound gallons and whole containers from installed panel area, product coverage, waste, and package size.14WallpaperCalculate wallpaper rolls from full-height strips, physical roll dimensions, trim, straight or half-drop pattern repeat, and two wall heights.19Drywall sheetsUse this drywall calculator to estimate 4×8, 4×10, or 4×12 sheet quantities from wall run, ceiling area, openings, layers, waste, and sheet size.32PaintUse this paint calculator to estimate gallons and whole cans from room dimensions, wall area, doors and windows, ceiling area, coats, and coverage.50Drywall costEstimate drywall installation cost from net area, layers, whole sheets, user-entered sheet price, finish materials, labor, removal, and delivery.
Flooring & Tile
Flooring, carpet, shower and backsplash tile, layouts, stairs, and grout.
20TileUse this tile calculator to estimate square footage, individual tiles, and whole boxes from room dimensions, exclusions, waste, and box coverage.21Flooring boxesUse this flooring calculator to total up to three rooms, subtract exclusions, add cutting waste, and estimate whole boxes from carton coverage.31Tile groutEstimate tile grout bags from tiled area, product coverage, waste, bag size, tile dimensions, joint width, and joint-depth volume cross-check.33CarpetCalculate carpet linear yards by comparing two straight room layouts against the selected carpet roll width and waste allowance.42Shower tileCalculate shower wall and floor tile separately, including three wall surfaces, openings, niche faces, waste, and product-specific box coverage.43Backsplash tileCalculate backsplash tile sheets or package units from run length, height, usable exclusions, waste, sheet coverage, and exposed edge trim.44Tile layoutCalculate a centered straight tile grid, row and column counts, approximate opposite edge cuts, and tile quantity with allowance.45Stair carpetCalculate stair carpet runner length and linear yards from tread depth, riser height, nosing wrap, step count, stair width, landing, and roll width.
Lumber & Carpentry
Board feet, log scale, lumber weight, framing, sheet goods, fences, and decks.
22Board feetCalculate board feet for lumber from thickness, width, length, and board quantity, with per-piece volume and metric cubic-volume cross-checks.23Wall framingUse this wall framing calculator to estimate studs and plate stock from wall length, chosen stud spacing, openings, detail extras, and waste.28Wood fenceUse this wood fence calculator to estimate posts, rail stock, and pickets for one straight run from spacing, board width, gaps, and waste.29Chain-link fenceEstimate chain-link fence fabric rolls, terminal posts, line posts, top rails, and tension bars from measured runs and gates.30Deck boardsUse this deck board calculator to estimate board courses and stock pieces from deck size, board direction, face width, gap, length, and waste.34Lumber weightEstimate lumber weight from actual board dimensions, quantity, user-supplied wood density, and an explicit moisture adjustment.35Log board feetCalculate gross log board feet using Doyle, an explicit Scribner approximation, or the International ¼-inch formula from small-end diameter and length.39Plywood sheetsUse this plywood calculator to compare an area minimum with a simple two-orientation full-sheet grid for one rectangular surface.

A result you can audit before you buy.
Editable assumptions
Use the yield, density, coverage, or pallet size printed on the product you are actually buying.
Honest rounding
We show net material first, then apply waste once, then round whole packages up.
Visible limits
Quantity estimates do not quietly become structural, code, or installation advice.
Plan the whole project
Use these field guides to measure cleanly, choose the right calculator, and carry one set of dimensions through the complete material list.
