Gate sizing allowance

[Mattatooi]

Going to make a gate with treated timber for driveway between house and fence. It will be a 2 door gate. Size inbetween each post is 2235mm.

Just working out a design in sketchup but wanting to know what sort of gap should i be allowing between each gate and post etc for opening/closing of gate and expansion/contraction of wood etc?

The wood is treated timber and has been outside. Some boards heavier than others (as in has more moisture content). The style of gate will be vertical board with small gaps inbetween.

Cheers

My gate swell by around 20mm max in wet weather.

As above, pretty much all of the places that custom make gates state in their measuring guides 10mm either side, so 20mm smaller than the opening.

Cheers thanks.

Being 2 gates I probably need to allow a bit more then.

Yes an additional 10mm between the two leaves https://www.jacksons-fencing.co.uk/measure-garden-gates.aspx
