How do I calculate square footage for tiles?

Multiply the length of the room by the width to get the area in square feet. For example, a room that is 12 feet long and 10 feet wide is 120 square feet. Always add 10 to 15 percent extra for cuts and waste.

How much extra tile should I order for waste?

Add 10% for simple straight layouts, 15% for diagonal or offset patterns, and 20% for herringbone or complex tile cuts. It is always better to have a few tiles left over than to run short mid-project.

Can I calculate tile square footage in metres?

Yes. The Flair Decos tile calculator supports feet, metres, centimetres, inches, and yards. You can mix units — for example, enter length in metres and width in feet — and the calculator will convert automatically.

Can I calculate tiles needed for multiple rooms?

Yes. Click Add Another Room to add as many rooms as you need. The calculator will give you a total area across all rooms as well as a room-by-room breakdown.

How many tiles do I need for a 12x12 room?

A 12 by 12 foot room is 144 square feet. With a 10% waste allowance you should order at least 159 square feet of tiles. Use the Flair Decos tile calculator to get an exact estimate for any room size.

Pro Tips Before You Buy

Always add waste. Even simple rooms need at least 10% extra for cuts at edges and corners.

Buy from one batch. Tiles from different batches can vary slightly in shade — buy all you need at once.

Keep spare tiles. Order a few extra to store for future repairs — the same tile may not be available later.

Measure twice. Double-check your room dimensions before placing your order — it saves time and money.
