Find the narrowest point.
Check the top, middle and bottom of the clear opening. Out-of-plumb posts may need correction, not just a smaller gate.
MEASURE ONCE. CHECK TWICE.
A good fit
starts here.
An opening is not a gate size.
Allow for the hinges, latch and the ground your gate swings over.
A Post-to-post openingB Gate leaf only
Allow for the ground.
Check the highest ground point across the whole swing. Deduct the required bottom clearance from your proposed top level; a slope may require a different hinge arrangement.
Check before ordering.
Our product selectors show height × width in centimetres. Confirm whether a driveway width is per leaf or per pair. A calculated maximum is not a manufacturing instruction.

Email photographs and measurements. We’ll help check the details before you choose a listed size. Calculations are guidance only and do not check posts, structure, swing geometry or safety.
