Guide

The tile calculation formula, explained.

The number of tiles you need is simple: room area ÷ area of one tile. For a 10 ft × 12 ft floor with 2 ft × 2 ft tiles that is 120 ÷ 4 = 30 tiles.

Real installs never come out exact. Add 5–15% for cuts, breakage and future repairs — more for diagonal layouts, small tiles and irregular rooms. That buffer is built into every estimate here.

For walls, measure each wall's length × height, add them together, then subtract windows and doors. Our calculator does all of it for you.

About This Tool

Why you can trust this tile calculator

There are hundreds of tile calculators online, but most only multiply a length by a width and call it done. This tool was built to behave like a real installer: it accounts for grout lines, cutting waste and layout patterns, deducts window and door openings, and adds realistic estimates for grout, adhesive and cost. The result is a free tile calculator you can trust for quoting, ordering and budgeting — whether you measure in feet or metres, plan in square feet or square meters, and whether you are tiling a floor, a wall, a ceiling or a shower.

Tile calculator square feet

For most projects the number that matters is tile calculator square feet — how much surface a room covers and how many tiles that needs. Enter the length and width of your space and the tool instantly converts it to square feet (or m²), then divides by the area of one tile to give the exact tile count. It also shows the "with waste" total, so the quantity you order includes the tiles you will cut, drop on delivery, or need years later for repairs. No round-up guesswork, no ordering short.

Floor tile calculator

Floors are the most common job, and this floor tile calculator handles anything from a compact hallway to a large open-plan living room. Choose your room size, pick a tile size (6×6, 12×12, 12×24 or 24×24 inches, or 300×300, 400×400, 600×600 and 600×1200 mm), then set your grout gap and waste percentage. The estimate recalculates live on every keystroke. A plain tile calculator for floor work gives you one number; this one also gives you boxes, grout, adhesive and cost for the exact floor you measured.

Wall tile calculator

Walls are where most calculators go wrong, because they pretend a wall is just another big rectangle. Our wall tile calculator lets you enter each wall's height and width separately and then deducts windows and doors, so you never pay for tiles that cover openings. It works with feet and inches or metres and centimetres, and the wall tile calculator square feet output matches exactly what you will buy at the store. For kitchen backsplashes, pick the small mosaic presets and raise waste to 15% to cover the many small cuts around outlets and cabinets.

Ceiling tile calculator

Ceilings follow the same area math as floors, and the ceiling tile calculator counts tiles across the full ceiling surface, with light fixtures and vents absorbed into your waste buffer. Most dropped ceilings use large square tiles, so the built-in presets make planning a commercial or basement ceiling quick and accurate.

Shower tile calculator

The shower tile calculator is one of the most requested tools here, and it is built to handle a shower floor plus one, two or three shower walls. Enter each wall's height and width, deduct the shower opening, and the estimate accounts for a real alcove rather than an imaginary rectangle. Need a tile calculator for shower walls only? Switch the surface to wall and enter each side. Whatever you call it — tile calculator shower, bathroom tiles, or a full wet area — the grout estimate also reflects the reality that small wall tiles and mosaic floors use more grout per square foot.

Bathroom tile calculator

Bathrooms are almost always a mix — a floor, walls and a shower area — which is why this bathroom tile calculator supports multiple sections in a single estimate. Add a floor section, add wall sections, add a shower alcove, and everything merges into one total you can take straight to the tile shop. Add the tiles-per-box and price-per-box, and the bathroom tile calculator turns the whole job into an instant cost in your own currency.

Everything above is instant and completely free — no sign-up, no pop-ups, no account required. If you are quoting a contractor or ordering tiles online, the print and share tools give you a clean summary of tiles, boxes, grout, adhesive and cost in seconds.

FAQ

Questions, answered.

How many tiles do I need for a 12×10 ft room?
For a 120 sq ft room with 12×12 in tiles (1 sq ft each) you need 120 tiles. Add 10% for cuts and breakage and you should order about 132 tiles — 33 boxes of 4.
Does the calculator work for walls too?
Yes. Switch the surface to "Wall" and enter each wall’s length and height. You can also deduct windows and doors so you are not ordering tiles for openings.
Can I switch between feet and metres?
Any time. The unit toggle converts every number automatically — room dimensions, tile size, area and totals. Nothing gets lost in the switch.
How much waste should I add?
A 10% buffer covers most floors and walls. Add more for diagonal or herringbone layouts, very small mosaic tiles, or irregular rooms with lots of cuts. Outdoor areas often need 15%.
Does it estimate grout and adhesive too?
Yes. It estimates grout in kilograms from your tile size and gap, and adhesive based on the trowel size you plan to use — so you can buy everything in one trip.
Is the estimate accurate enough to order from?
For standard rectangular spaces, yes. Irregular shapes are always safer with a bigger buffer, and we recommend confirming your final numbers with your tile store.
How much tile do I need calculator?
Our calculator answers "how much tile do I need" in seconds. Enter your room's length and width, pick a tile size, and set the waste percentage. The tool divides the floor area by the area of one tile, adds cutting waste, and shows the exact tiles and boxes to order — including the 10% buffer most floors need.
How much tile calculator?
For any surface, the "how much tile" calculator works the same way: measure the area, divide by the tile's footprint, and add waste. Switch between feet and metres, choose a floor, wall, shower or ceiling project, and the tool returns the total tile count, boxes, grout and adhesive instantly — with no sign-up.
How many square feet tile calculator?
To find how many square feet of tile you need, multiply the room's length by its width. Our square feet tile calculator does that and more — it converts feet and inches or metres, divides the area by the tile size, and adds waste, so the final number in square feet is the amount you actually order.
How does the tile calculator work in square feet?
The tile calculator works in square feet by turning your room dimensions into a surface area, then dividing it by the tile's area in sq ft. Grout lines and layout patterns are accounted for automatically, and the "with waste" total shows the square feet needed after adding cuts and breakage.
How does the bathroom tile calculator work?
The bathroom tile calculator works by estimating several surfaces at once — a floor, each wall and a shower alcove. Add sections one by one, deduct windows and doors, and the tool merges everything into one total. You get tiles, boxes, grout, adhesive and cost for the entire bathroom in a single estimate.
Tile calculator cost?
This tile calculator is free to use, and it also estimates the cost of your job. Enter the tiles per box and the price per box in your currency (₹, $, €, £ or AED) and the tool multiplies the boxes needed by the price for an instant total — so you can budget before you buy.
