Standard carport dimensions
Five footprints cover almost every South African carport: 3m × 6m single, 6m × 6m double, 3m × 12m tandem double, 9m × 6m triple and 12m × 6m four-bay. All five are 6 m deep, because that is what a car needs to sit fully under cover with the boot open. Width is what changes, and it changes in 3 m steps — one bay per vehicle.
| Carport | Width × depth | Vehicles |
|---|---|---|
| Single | 3m × 6m | 1 car / bakkie |
| Double (side-by-side) | 6m × 6m | 2 cars |
| Double (tandem) | 3m × 12m | 2 cars in line |
| Triple | 9m × 6m | 3 cars / boat bay |
| Four-bay | 12m × 6m | 4 vehicles |
Size your carport
Width, depth and height rules of thumb
Allow 3 m of width per car for comfortable door-opening, 2.5 m at an absolute minimum. Keep 6 m of depth so a car sits fully under cover with the boot up; a bakkie or a long SUV wants 6.5 m. For height, measure your tallest vehicle and add 300 mm — a standard 2.1 m beam clears a sedan, while a 4x4, a bakkie with a canopy or a roof box needs 2.4–2.7 m. These dimensions feed straight into carport prices in Johannesburg, and the roof style that fits the size is under carport designs. Each standard footprint has its own page — the single carport at 3m × 6m, the double carport at 6m × 6m and the triple carport at 9m × 6m. Once the size is settled, the material and price bands are on the main range of carports in Johannesburg.
Common questions
What is the standard size of a double carport?
A standard double carport is 6m × 6m for two cars side by side. Where the driveway is narrow, a tandem double of 3m × 12m covers two cars in line. Both are 6 m deep to clear a parked car with the boot open.
What height should a carport be for a bakkie or 4x4?
A carport for a bakkie with a canopy or a 4x4 needs a beam height of 2.4–2.7 m, against 2.1 m for a sedan. Measure your tallest vehicle and add 300 mm of clearance.
How much width does each car need under a carport?
Allow 3 m of width per car for comfortable door-opening, or 2.5 m at an absolute minimum. So a double carport is 6 m wide and a triple 9 m wide.
