Split an opening into single or double gate leaves.
Clearance is subtracted from the rough opening, then a double gate splits the remaining width evenly between two leaves. The gap separated from the nominal opening is what actually fits a gate panel, especially on slightly out-of-square drives.
Gate Width
Gate = opening - clearance; each leaf = gate / number of leaves
Gate = opening - clearance; each leaf = gate / number of leaves Clearance is subtracted from the rough opening, then a double gate splits the remaining width evenly between two leaves.
The gap separated from the nominal opening is what actually fits a gate panel, especially on slightly out-of-square drives.
This calculator takes 3 inputs: Opening width, Gate type, Clearance per side. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
