Gate Width
Split an opening into single or double gate leaves.
About Gate Width
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.
Formula
Gate Width
Gate = opening - clearance; each leaf = gate / number of leaves
- clearance
- Gap left at each side so the gate swings freely
Worked example
With the default values below, Gate Width returns Gate Total Width of 140.0. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Gate Width calculated?
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.
Why does Gate Width matter?
The gap separated from the nominal opening is what actually fits a gate panel, especially on slightly out-of-square drives.
What values do I need to enter?
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.
