How to Measure Your Room for Tiles

Measuring your room for tiles

Thinking of giving your kitchen or bathroom a refresh? Planning on revamping your hallway floors? Whichever room in your home you are buying tiles for, it’s important to measure properly so you get the right amount of tiles. It can be confusing working out the correct measurements so we’ve put together some tips to help you breeze through it.

What You’ll Need:

  • Tape measure
  • Notepad
  • Pen or pencil
  • Calculator
  • Strong cup of tea or coffee
  • Motivational background music (we were enjoying a bit of Beyoncé while writing this)

When taking measurements be sure to use centimetres as most tile measurements are given in millimetres, centimetres or metres – so it makes it easier to keep it consistent.

Measuring The Walls

As most walls tend to be square or rectangular measuring them is not too hard, you just need to remove any doors or windows from the overall measurement. If you are not tiling from floor to ceiling or wall to wall make sure you are only measuring up to where you want the tiles to stop.

  1. Measure the height of the wall area that will be tiled
  2. Measure the length of the wall area that will be tiled
  3. Multiply these two numbers together to get the total
  4. Convert this number to m2 by dividing by 10,000
  5. Measure the window or door and convert to m2
  6. Repeat for any additional windows or doors, then add these together
  7. Subtract the total window/door m2 from the wall space
  8. Add an additional 10% to this number by multiplying it by 1.1 to allow for cuts, damages & wastage
  9. Repeat for any other walls, then add all figures together to get a total

Measuring The Floor

For a simple square/rectangular room with no major obstructions it’s really easy to measure the floor.

  1. Measure wall A and write down the measurement
  2. Measure wall B and write down the measurement
  3. Multiply measurement A and measurement B to get the area in cm2
  4. Convert this number to m2 by dividing by 10,000
  5. Add an additional 10% to this number by multiplying it by 1.1 to allow for cuts, damages & wastage

Unfortunately most of us will not have a totally empty or simple room to work with so next we will look at how to measure the floor in a room with baths, showers, cupboards, etc.

  1. Draw a rough sketch of the room showing any obstacles
  2. Split the floor space in the room into square or rectangular sections
  3. Measure each section and note down the measurement
  4. Divide each measurement by 10,000 to get the m2
  5. Add up the individual shape measurements to get the area, then multiply by 1.1 to allow for wastage

All tiles on the London Tile website are sold per box, but there is a handy calculator on each page that allows you to enter the total m2 you need and works out how many boxes that equates to. Browse our range of wall tiles and floor tiles online or pop into one of our showrooms.

    Really informative post – something a lot of people don’t realise they don’t know until they get to needing to do it! Great idea to add an extra 10% for spare / damage.
