Planning tips for Floors & tile
Flooring and tile projects are mostly about accurate area, realistic waste, and converting to the units you actually buy (boxes, bags, rolls).
What to measure
- Measure room area (length × width) and sum rooms; measure separately for closets and alcoves.
- For tile, note tile size, layout direction, and whether you’re tiling walls, floors, or both.
- For grout/underlayment, confirm coverage on the bag/box and your joint width or thickness.
Useful defaults
- A 10% overage is common; use 15%+ for diagonal patterns, many corners, or lots of cuts.
- Round up to full boxes and keep dye lots consistent when possible.
- Plan extra for breakage and future repairs, especially for discontinued styles.
Common misses
- Using net area when you really need gross area (or forgetting closets and niches).
- Not adding waste for patterns, borders, or staggered layouts.
- Ignoring accessory materials like underlayment, thinset, and transitions.

FAQ
Are these calculators accurate?
They are practical estimates based on your inputs and common assumptions. For critical projects, confirm with product specs or a professional.
Why do you recommend adding waste/overage?
Real projects include cuts, mistakes, uneven surfaces, and rounding to boxes/bundles. A small buffer prevents shortages and extra trips.
Can I share my result?
Yes. Most calculators support shareable links that keep your inputs so you can revisit or send the estimate to someone else.
