Frequently asked questions
- Why add a waste percentage?
- Cutting tiles around edges and breakage typically wastes 5–15% of tiles, so adding a buffer avoids running short.
- How is the number of boxes calculated?
- Total tiles needed is divided by tiles per box and rounded up, since you can only buy whole boxes.
- Can I use different units?
- Enter length and width consistently, e.g. all in meters; the tool works with any unit as long as it's consistent.
