Tile Calc
A tile and material estimator that gets the maths right, room by room.
The problem
Most online tile calculators are a single form: area in, number out. That breaks the moment it meets a real job. Floor and wall use different tile sizes but get blended into one figure. Box counts vary by manufacturer, so dividing by four is often wrong. Adhesive coverage depends on tile size and trowel notch. Grout has an actual formula. Guess any of these and somebody pays for the correction.
What it does
Tile Calc is a web-based tile and material estimator. A guided flow — describe the project, list the rooms, choose tile sizes and materials — returns a room-by-room breakdown of exactly how many tiles, boxes, bags of adhesive and kilograms of grout the job needs, with floor and wall calculated separately.
It does the real arithmetic rather than a blended estimate. The tile catalogue holds 34 sizes taken from actual supplier packaging data — from 75×225mm mosaics up to 800×3000mm slabs — so box counts are the manufacturer’s, not a round number. Adhesive coverage follows real coverage tables by tile size and adhesive type. Grout uses the proper formula across tile size, joint width and joint depth.
It is built for real project complexity: multiple rooms, room-type grouping with per-room override, and openings entered individually so a room with two differently sized windows gets an accurate wall-area deduction.
Registration is verified by WhatsApp OTP, which means every completed estimate carries a real, reachable mobile number — useful for anyone connecting buyers to dealers. Each estimate also gets a short shareable code so a customer can reopen and update it later without an account.

What changes
The difference it makes
Before
- Floor and wall blended into one number
- Tiles divided by four to guess boxes
- Adhesive and grout estimated roughly
- A flat wastage percentage
- One room at a time
- A number scribbled on a card
After
- Calculated separately, the way a real job works
- Real packaging data, so box counts are right
- Coverage by tile size, grout by an actual formula
- Wastage from the layout and room size
- A whole multi-room project in one estimate
- A ready-to-send quotation

Common questions
How is wastage calculated?
From the chosen layout and room size rather than as a flat percentage — a diagonal or herringbone pattern wastes noticeably more at the edges, especially in a small room.
Does it handle skirting?
Yes, as its own calculation and its own line, rather than merged into the floor count. You choose the height and tile size.
Is it free?
A full material breakdown is free as a guest, with no account required. An account adds saved history and pricing.
Can we put it on our own website?
Yes — a fully branded version on your own domain, with your logo and colours. Customers estimate accurately before ordering, which means fewer mismatched batches and fewer returns.
