How Big Should a Carport Be? A Single and Double Carport Size Guide

Most carport regrets come down to one thing: size. A carport that's a little too narrow means doors that can't open fully. One that's a little too short leaves the tow bar in the rain. And one that's a little too low scrapes the roof racks every time you drive in. The good news is that all of these are easy to avoid before you order.

Because every D&C Patio Kit is made to your measurements, you're not stuck with a handful of set sizes. Here's how to work out the carport size that actually suits you.

Step 1: Measure what you'll park

Start with the vehicles, then add room to live with them:

  • Length: most sedans and SUVs fit comfortably under a carport around 6m long. Dual-cab utes, tow bars, or a car and trailer may need more.
  • Width: allow roughly 3m per vehicle so doors can open and you can walk around without squeezing past a post.
  • Height: measure your tallest vehicle including roof racks, pods and aerials, and leave a margin under the beam.

Parking a caravan, boat or motorhome? Height is the number that matters most. Talk to our team before you order.

Single carport or double carport?

A single carport, around 3m wide, suits narrow side access, one-car households, or covering a car beside the garage. If you're parking a large SUV or ute, or you want easy access for kids and shopping, go a little wider.

A double carport, around 6m x 6m, is the most popular size for Australian homes. It covers two cars side by side, or a car plus a boat, trailer or covered workspace.

Can't decide? Think about the next car you'll buy, not just the one in the driveway today. A carport that's slightly bigger than you need is rarely a problem. One that's too small is annoying every single day.

Step 2: Choose your carport style

A carport doesn't have to stand on its own. Our online calculator lets you choose from four roof styles:

  • Attached roof: fixed to your metal fascia, timber fascia, timber wall or masonry wall. It's neat, uses fewer posts, and gives you a covered path to the door.
  • Flyover roof: raised above your existing gutter for extra height. It's ideal for 4WDs, roof racks, trailers and homes with low eaves.
  • Freestanding: stands on its own posts. It's the right choice when there's nothing suitable to attach to, or the carport sits away from the house.
  • Gable roof: a peaked roof with two sloping sides, available freestanding or fixed to a wall.
