Standard Fence Gate Widths
Our free fence gate width calculator recommends the standard gate width for your use case — walk gate, ride-on mower gate, or driveway gate — then converts the gate opening into the actual gate leaf size you should build, accounting for hinge and post clearance.

How to use this calculator
Pick what will pass through the gate: a walk gate for people and push mowers, a wider gate for a riding mower or other equipment, or a double gate for a driveway. Then choose one of the standard opening widths for that use case.
Set your total hinge and latch clearance (about 5 inches is typical — roughly 4 to 6 inches total for hinges, the latch, and post gaps). If you are planning a whole fence run, enter the total run length and your fixed panel width so the calculator can work out how many fence panels fit beside the gate and how wide each one should be.
How it works
The calculator works from two different widths that people often confuse. The gate opening width is the clear distance between the two gate posts — this is the standard size (for example, 48 inches for a walk gate). The gate leaf width is the width of the actual gate frame you build or order, and it must be smaller so it swings and latches freely: leaf width = opening width − hinge and latch clearance.
For the 4 ft standard walk gate with 5 inches of clearance, that gives a leaf of 48 − 5 = 43 inches. Double driveway gates split the leaf across two frames, so each leaf is (opening − clearance) ÷ 2 — a 12 ft double gate with 5 inches of clearance becomes two 69.5-inch leaves. For the fence run, the remaining length after the opening is divided into an equal number of fixed panels: panels = ceil(remaining length ÷ panel width).
Standard fence gate widths
| Use case | Typical range | Standard choice |
|---|---|---|
| Walk gate | 36–48 in | 4 ft (48 in) |
| Ride-on mower / equipment gate | 5–6 ft | 5 ft (60 in) |
| Single vehicle gate | 8–10 ft | 10 ft |
| Double driveway gate | 12–16 ft | 12 ft |
These are planning estimates for residential wood and vinyl fences. Very heavy or tall gates, slopes, and local code requirements (for example pool fencing) can change what width and hardware you need — when in doubt, measure your actual equipment and check local rules.
Frequently asked questions
What is the standard width for a residential fence gate?
The standard residential fence gate width is 4 feet (48 inches). Walk gates typically range from 3 to 4 feet wide, but 4 feet is the most common choice because it comfortably fits foot traffic, wheelchairs, push mowers, and small equipment.
How wide should a gate be for a riding mower?
Allow at least 5 feet (60 inches) for a riding mower, and 6 feet is safer if the mower has a wide cutting deck. Measure the widest part of your mower — including the deck and any discharge chute — and add about 6 inches of margin before choosing the gate width.
What is the difference between gate opening width and gate leaf width?
The gate opening width is the clear distance between the two gate posts. The gate leaf width is the width of the actual gate frame you build or buy, which is smaller: leaf width = opening width minus the clearance needed for hinges, the latch, and the gap between the posts. Plan for roughly 4 to 6 inches of total clearance.
Should I use a single or double gate for a driveway?
Use a double gate for driveways. A single 10-foot driveway gate is standard for one car, while a 12-foot double gate fits two cars side by side or a trailer. Splitting the width into two frames keeps each leaf under 6 feet, which greatly reduces sagging and hinge strain compared to one very wide single gate.
