Apa itu Kalkulator Keramik Lantai & Ubin?

Enter a room's dimensions and a tile's size to see how many tiles — and how many boxes — to buy, including a waste allowance.

How to calculate tiles and boxes needed for a floor

How the calculation works

Formula
tiles = ceil((room_area / tile_area) × (1 + waste%))

How to use it

  • Enter the room's length and width, in meters.
  • Enter the tile's length and width, in centimeters.
  • Enter a waste percentage and, optionally, tiles per box.

Choosing a waste allowance

10% is a common default for a simple rectangular room laid straight. Diagonal layouts, herringbone patterns, rooms with many corners, or a first-time DIY installation typically warrant 15–20% instead, since more tiles get cut down or broken.

Worked example

3 m by 4 m room with 60 x 60 cm tiles

With 10% waste, buy 37 tiles, or 4 boxes if each box holds 10.

ceil((12 / 0.36) * 1.10) = 37

Material estimate notes

Room and tile dimensions stay in the browser. The result is an area-based estimate, so measure irregular spaces separately before buying material.

Pertanyaan yang Sering Diajukan (FAQ)

How much waste should I add?

10% for a simple rectangular room and a straight layout; 15–20% for diagonal or patterned layouts, irregular rooms, or if you're new to tiling.

Does this account for pattern layouts like herringbone?

No — it assumes a simple grid layout. A patterned layout wastes more material than this estimate accounts for, so raise the waste percentage to compensate.

What if my room isn't a rectangle?

Split it into rectangular sections, calculate each separately, and add the tile counts together — the area-based math stays accurate as long as each section is measured correctly.

Why are tiles rounded up?

You cannot buy part of a tile. The calculator applies the waste percentage and then rounds up to whole tiles.
