Yes, at my age I shouId be able to work it out...but I can't so HELP!
I want to put decking in a 5m x 2.5m area. Using the B&Q decking tiles each measuring 25 x 120 x 2400 mm how many do I need please?
Are you flexible on the area to be used?

If you cut it down slightly to 4.8m * 2.4m then you won't have to cut the wood and you can do it with 40 pieces.
Decking boards, or decking tiles? 2400mm is long for a tile.

Edit: If it's boards, I make it that you need 44.
Yes, I think we could be flexible as we rounded the measurements up. Thank you very much!

Sorry...just looked at the other thread and they are BOARDS.
What about these tiles? L) 450 x (W) 450 x (T) 28mm How many of this size?

Again, helps if you can be a bit flexible to avoid cutting.

4.95m * 2.25m would need 55 tiles
4.95m * 2.7m would need 66 tiles.

Always worth avoiding cutting if you're not filling an exact space.

You'll need about 62 of these.

The way to work it out is:

Total area to be covered: 5 x 2.5 = 12.5 square metres.
Area of 1 tile: 0.45 x 0.45 = 0.2025 square metres

Number required = 12.5/0.2025 = 61.73, rounded up to about 62.

Hope this helps
Tiles will work out more expensive than boards/planks. If you do go for boards, check your builders merchants (eg Jewsons). When I did some decking last year, they were cheaper than B & Q or Wickes

I haven't checked your calcs, but you can't use a simple "Divide" to get the amount of tiles, as you are not taking into account any cutting/extra tiles needed.
