Flooring calculators.
Compare area-based packs with layout-based tiles and roll-based carpet. Doorway deductions and offcut assumptions depend on the material.

Flooring Calculator
Calculate flooring packs from your floor area and the coverage on your chosen pack.
Open calculatorFlooringUnderlayment Calculator
Estimate underlay packs by effective area or rolls from room width and your specified seam overlap.
Open calculatorFlooringTrim Calculator
Estimate skirting or baseboard lengths after subtracting doorway gaps.
Open calculatorFlooringAdhesive Calculator
Estimate adhesive packs using the coverage stated for your product and application.
Open calculatorFlooringTile Layout and Packs Calculator
Count a straight tile grid for each room using actual tile dimensions and specified joints.
Open calculatorFlooringCarpet Roll Length Calculator
Plan carpet strips by roll width, room direction and any specified pattern repeat.
Open calculatorFlooringTile Grout Calculator
Estimate filled joint volume and grout packs using supplied mixed-product density.
Open calculatorFlooringTile Color Blend Pack Calculator
Order separate tile colors in an explicit area ratio while rounding each color’s packs independently.
Open calculatorFlooringTile Border Layout Calculator
Count full border pieces along separate straight edges and supplied corner pieces.
Open calculatorFlooringFloor Plank Row Cut Calculator
Count boards and end offcuts when each row starts with a supplied staggered starter cut.
Open calculatorFlooringFloor Layer Height Calculator
Add specified layer thicknesses and compare a finished floor height to an adjoining threshold.
Open calculatorFlooringCarpet Seam Tape Calculator
Calculate the total joins between parallel carpet strips from an already selected strip layout.
Open calculatorFlooringFloor Transition Strip Calculator
Count whole threshold pieces for separate openings and identify pieces too short for one opening.
Open calculatorFlooringSpecified Step Surface Cover Calculator
Separate tread, riser and landing areas for covering an already specified stair geometry.
Open calculatorFlooringCheckerboard Tile Purchase Calculator
Count an actual two-color alternating grid rather than splitting area equally.
Open calculatorFlooringRotated Tile Grid Takeoff Calculator
Clip a rotated tile grid to the actual floor boundary and count edge cuts.
Open calculatorFlooringTile Grid Cross and Edge Spacer Pack Calculator
Count interior grid intersections and boundary joint ends separately from a supplied tile grid.
Open calculatorFlooringTile Joint Edge Leveling Clip Pack Calculator
Count clips along internal tile edges using your already specified clips per edge, with no clips on outer boundaries.
Open calculatorFlooringTile Profile Exposed End Cap Pack Calculator
Count exposed ends of supplied profile runs after removing paired internal joins and individually excluded ends.
Open calculatorFlooringFlooring Packs after Supplied Perimeter Gap Calculator
Compare measured room area with the actual supplied inset floor rectangle before pack rounding. Does not choose an expansion gap.
