Stop guessing.
Start your reno right.
Free calculators that tell you exactly what to buy, plus a project planner to track every trade from first quote to final coat — all in one place, no signup required.
Sound familiar?
These are the real costs of estimating by gut feel.
Back to the store — again
You bought what looked like enough tile. It wasn't. Now the job is on hold while you hunt for a matching dye lot that may not exist.
The missing items list
You measured the paint, but forgot primer, roller covers, tape, and tray liners. Four separate trips for a one-day job.
Overbuying to play it safe
So you round way up to avoid trip two. Now you have 8 leftover bags of thinset and no way to return opened product.
One calculation. Everything you need.
Most calculators give you one number. We give you the complete picture — every material, every consumable, every detail — so you walk into the store knowing exactly what to put in the cart.

How it works
From measurements to shopping list in under two minutes.
Enter your measurements
Type in your room dimensions — length, width, height — or add multiple areas at once. Works in feet or metres.
Get your complete materials list
Every calculator outputs the primary material plus the consumables that go with it: grout, thinset, tape, primer, spacers, screws — nothing missing.
Save, plan, and shop
Save any result to My Sheets for reference. Use the Project Planner to track your whole renovation — what's quoted, what's in progress, what's done.
Real renovation scenarios
Here's what RenoSheets does for common projects.
Bathroom tile floor
The challenge: How many 12×24 tiles for an 85 sq ft bathroom? What grout, thinset, and backer board?
What you get: Get exact tile count with waste, thinset bags adjusted for large-format tile, grout from joint-width formula, and backer board sheets — all in one list.
Painting three bedrooms
The challenge: Two coats, three rooms of different sizes. How many gallons of paint and primer?
What you get: Enter each room once, get total gallons by color, primer, roller covers, tape and trays — split by room so you can shop by color.
Full kitchen renovation
The challenge: Tile, paint, drywall, and new concrete countertop base — all happening at once. How do you stay organized?
What you get: Create a project in the Planner, add a task card for each trade, move them through Planning → Quoted → In Progress → Done as the job progresses.
Built for people who measure twice
Everything a serious renovator needs, nothing they don't.
Complete lists, not just one number
Every result includes the full buy list — the primary material plus every consumable that goes with it.
Transparent, adjustable waste
See exactly what assumptions were used. Adjust waste %, number of coats, and more — no black-box padding.
