Home project calculators
Choose the material you need to count. Each tool starts with an example you can replace, shows its math and gives you a plan to keep.
Roofing
Turn your roof measurements into bundles or panels. Then check the work included in each quote. See the complete project path.
Roofing calculator
Turn roof measurements into shingle bundles, then take the same material list into your quotes.
Roof pitch calculator
Convert rise and run to roof pitch, angle and sloped area. Carry the pitch into your roofing list.
Metal roofing calculator
Count panels for each rectangular roof plane, with a separate list for trim and fastening.
Roof debris calculator
Estimate tear-off weight from roof area, layers and your material’s weight. Compare the weight with a hauler’s load limit.
Tile & flooring
Work out tiles or flooring boxes for each room, with separate lists for shower walls and floors. See the complete project path.
Tile calculator
Plan tile positions, border cuts, boxes and setting materials. Compare straight, offset, diagonal and herringbone layouts.
Shower tile calculator
Keep wall tile and floor tile separate, with room for curb, niche and other small surfaces.
Flooring calculator
Add rooms, allow for cuts and round the order to whole boxes using the coverage on the label.
Ceiling tile calculator
Count ceiling panels and grid intersections for a rectangular room using the dimensions in your accepted ceiling layout.
Laminate flooring calculator
Compare plank direction, row cuts, cartons and underlayment for a laminate floor. Enter the gap and stagger required by your product.
Vinyl plank flooring calculator
Plan vinyl plank rows and cartons, with a separate adhesive calculation for glue-down flooring.
Hardwood flooring calculator
Plan single-width or repeating mixed-width wood flooring and keep fastening and site-finish quantities separate.
Epoxy floor calculator
Count whole coating kits from net floor area, coat count and the coverage of the mixed kit you are buying.
Paint & drywall
Measure the surfaces you are finishing. Keep paint, primer, drywall and preparation work separate. See the complete project path.
Paint calculator
Add rooms, choose walls or walls and ceilings, and count paint cans for the coats you want.
Exterior paint calculator
Add rectangular elevations and triangular gables, then subtract windows and doors before counting paint.
Drywall area calculator
Estimate an area-based sheet allowance for walls and ceilings. Check a sheet layout before ordering, then add finishing materials from the product coverage.
Concrete & masonry
Turn measured shapes into concrete yards, bags or masonry blocks before asking about delivery and installation. See the complete project path.
Decks
Count surface boards, check quantities from a framing plan, and work through stair geometry. See the complete project path.
Deck board calculator
Count surface boards and fastening points from deck dimensions, board direction and your framing layout.
Deck framing quantity calculator
Count joist lines and planned beam or post quantities. Enter dimensions from a design your local authority accepts.
Deck stair calculator
Divide the total rise into equal risers and inspect the stair run before discussing the layout with your designer.
Fences
Place gates and corners before counting posts, pickets or chain-link parts. See the complete project path.
Wood fence calculator
Lay out each straight fence section and gate, then count posts, rails and pickets without hiding the corners.
Chain-link fence calculator
Place gates, corners and grade changes, then count each post type, fabric, top rail and tension components.
Fence post spacing calculator
Split each clear run into equal bays while keeping gate and corner posts in their own positions.
Fence layout planner
Draw connected fence runs from lengths and directions. Keep gate positions, grade changes and shared posts on one measurable plan.
Wire fence calculator
Count mesh rolls or individual wire strands, separating line posts, terminals, gates and planned braces.
These tools measure quantities. Structural design, local code approval and current installed prices need project-specific evidence. Keep those questions with your written quote comparison.
