Tired of buying too much flooring โ or worse, running out mid-job? Floor Calculator turns any room into an accurate material order in seconds, with AR room scanning and one-tap client quotes. Here's how it works: scan your room with AR (or measure manually if you prefer), pick your floor type, choose your layout pattern, and Floor Calculator instantly shows you the exact piece count, box count, waste allowance, underlayment rolls, baseboard linear feet, and total cost. Done. No accounts. No uploads. No tracking. Everything happens on your iPhone. Whether you're a flooring installer pricing a job in front of the customer, a contractor estimating a multi-room renovation, or a DIY homeowner heading to the lumber yard, Floor Calculator is built to be the fastest way to turn a tape-measure reading โ or an AR scan โ into a buy list and a quote. AR ROOM SCANNING Walk the room and let your iPhone capture the shape. RoomPlan-powered scanning on LiDAR devices, ARKit corner-tapping on others. Manually adjust any wall length after scanning if you want pinpoint accuracy. FULL MATERIAL TAKEOFF Supports tile, plank, carpet, roll, LVP, laminate, and hardwood. Handles rectangle, L-shape, U-shape, polygon, custom-drawn, and stair-tread coverage. Layout patterns include straight, diagonal, herringbone, and staggered plank โ each with the correct minimum waste factor built in so you never under-order. VISUAL LAYOUT PREVIEW See exactly how your tile or plank lays out before you order โ a scaled diagram shows every full piece and every cut. Drag to shift the starting point, mark doorways, windows, cabinets, or islands as cutouts, or draw a custom room outline by hand for a shape no preset covers. Straight, brick, diagonal, herringbone, or staggered patterns, plus square, rectangular, or hexagonal tile. ADD-ONS THAT FINISH THE JOB Optional underlayment roll count, baseboard linear feet (perimeter minus doorways), transition strip totals, mortar bags for tile, and adhesive for glue-down floors โ toggle on per room. MULTI-ROOM PROJECTS Save unlimited projects with as many rooms as you need. Combine totals across rooms into one consolidated material list and cost estimate. TRACK THE JOB, NOT JUST THE MATERIAL Move each project through Draft, Quoted, Won, Installed, and Archived. Attach site photos straight from the camera, check off cut pieces as they're laid, and save your go-to tile or plank spec as a template to reuse on the next job. CLIENT-READY QUOTES Generate PDF outputs from any project: a Cut List for your crew (with an optional room blueprint page), or a full Client Quote with labor (hourly or per-square-foot), margin, tax, and a signature line at the bottom. Export a cut diagram as PNG or the full material list as CSV. Hand it to the customer on the spot. IMPERIAL OR METRIC, ONE TAP Switch units anytime without losing precision. Enter measurements as fractions, decimals, feet-inches, or millimeters โ Floor Calculator parses them all. WALLS, BACKSPLASHES & TRIM Switch to Wall mode for a tile or vinyl-panel backsplash or accent wall โ same fast material takeoff, its own field labels and add-ons. Add crown molding alongside baseboard for full-perimeter trim counts. AR COLOR PREVIEW & BLUEPRINT IMPORT See your floor in a different color or pattern live in AR before you commit to an order. Already have a floor plan on paper? Import the photo, mark one known distance, and trace the outline instead of re-measuring by hand. Floor Calculator was built by a tradesperson tired of returning unopened boxes and tired of losing jobs because the quote took three days. Every input field, every default, every PDF row was chosen because it saved a real job real time. No crashes, no AR glitches โ just accurate numbers every time. 3-day free trial, then $1.99/week. Cancel anytime. Lifetime purchase also available. Terms of Use: https://taxlite.net/floor_calculator/terms.html Privacy Policy: https://taxlite.net/floor_calculator/privacy.html
