# How to calculate the number of ceiling tiles

When calculating the number of ceiling tiles required to repair the ceiling in a room, you need to follow a few simple rules.

It is best to mark and count the tiles on paper first. Traditionally, it is customary to lay slabs from the middle of the ceiling to the edge, and the “wall” rows should be the same width. The position of the tiles is determined on paper with an accuracy of a centimeter and only after that the drawing is transferred to the ceiling.

The calculation of the number of ceiling tiles is best illustrated by an example:

• A room with a size of 4.7 m. by 3.8 lm Total area is 17.86 m2
• In the drawing, we determine the number of whole tiles – there are 9×7 = 63 pieces.
• If there are no more than 25 cm gaps at the edges (i.e. no more than half the size of the tile), then one tile will go to two opposite sides, cut into two pieces of the corresponding size. If there are gaps of more than 25 cm at the edges (i.e. more than half of the tile size), then on each side you need to take into account the full tile and then the total number of tiles may slightly increase.
• In total, according to the drawing, we consider 10×8 = 80 full tiles (20 m2)
• Note: This calculation was made taking into account the fact that the general pattern on the ceiling is not violated anywhere. If you violate the pattern (for example, behind furniture, where it is not visible), then you can further reduce the number of tiles.

To determine the number of ceiling plinths, it is enough to calculate the perimeter of the room and round the figure to a multiple of the length of one plinth. In this example, it is 17 m..

Depending on the decor of the tiles and on your taste, we can also advise you on such a variant of the arrangement of tiles on the ceiling. Let’s say right away that this option is somewhat more complicated in the sticker, and it may also require more tiles, but the result will amaze you with its freshness and novelty. In addition, this option is perfect for a ceiling that has an incorrect configuration. The calculation of the number of tiles required for this option is similar.

If you do not have 100 percent confidence in your skills, then for any calculation we recommend that you buy one or two more pieces so as not to waste time on the way to the store and back because of one accidentally broken tile or baseboard.
