How much waste should I allow for tiles?
Straight lay: 10%. Offset/brick pattern: 10–15%. Diagonal: 20%. Irregular rooms with lots of cuts: 15–20%.
How many fence posts do I need?
Posts are typically spaced 2.4m apart (matching standard paling lengths). Divide your fence length by 2.4 and add 1 for the end post.
