How many clips do I need for my deck coverage?

As a reasonable rule of thumb guide, provided your joists are placed at the standard 450mm between centres, allow 4 clips per square metre, plus 10% for “starter joist” and wastage.


For an accurately calculation on your clip numbers, divide the length of your joist (in mm) by 555mm (the length of one clip), multiply this number by the number of joists in your deck, and allow 5% for “tops and tails” wastage.

TIP – always try and design the width of your deck so that you have full decking boards widths right across your deck. The “pitch” on the Merbau clip is 92.5mm.
