If you're in the market for a double garage upgrade or just curious about the options out there, you're in the right place. We're delving into everything you need to know about double garage doors, including standard sizes and customisation options.

How Wide Is A Double Garage Door?

When it comes to double garage doors, there's no one-size-fits-all solution. Garage doors come in a variety of sizes to accommodate different needs and garage dimensions. Whilst there's no standard size, we can provide some general guidelines to help you understand what might work best for you.

Typically, standard double garage doors range from 14 to 16ft wide and 7ft tall, providing enough space to comfortably fit two vehicles side by side.

Custom Doors and Measurement Factors

When upgrading your garage door, opt for a made-to-measure solution to guarantee precision. Factors such as the opening size, garage depth, roof and side space, and any internal obstructions and restrictions need to be taken into account.

At Garolla, we specialise in made-to-measure electric roller garage doors, ensuring a perfect fit for your garage space. Whether you're in need of a single, double or bespoke garage door, we’ve got you covered.

Frequently Asked Questions

Common double garage door sizes are around 14–16ft wide and 7ft high, equivalent to approximately 4.27–4.88 metres wide and 2.13 metres high. However, existing openings vary, particularly in older properties. A made-to-measure double garage door is manufactured to suit your garage rather than relying on a standard size.

Whether two cars fit comfortably depends on the clear opening width, the internal garage dimensions and the size of your vehicles. Allow space for wing mirrors, opening car doors and walking between vehicles. A double-width garage door provides access, but the garage itself also needs enough usable width and depth for both cars.

One wide double garage door provides an uninterrupted opening, giving you more flexibility when manoeuvring vehicles. Two single garage doors let you open each side independently but retain a central pillar that separates the entrances. The best choice depends on your existing garage layout, vehicle sizes and how you use the space.

It may be possible, but the central pillar could support the structure above the garage openings. A qualified structural professional must assess whether it can be removed and what additional support is needed. Once a suitable opening has been created, a garage door surveyor can confirm the measurements and fitting requirements for a double garage door.

Yes, provided the model is designed for the width of the opening. A double roller garage door opens vertically and rolls into a compact top box, keeping the ceiling area clear of horizontal door tracks. It also avoids the outward swing of a traditional up-and-over door, helping you make better use of driveway space.

Garolla Titan Shield is designed for garage openings up to 5.5 metres wide. Its reinforced construction and deep guide rails provide strength and stability across wider openings. A free home survey will confirm whether Titan Shield is suitable for your garage and establish the finished opening dimensions.

An insulated double garage door is worth considering if you use your garage as a workshop, hobby space or regularly accessed storage area. Foam-filled slats help reduce heat transfer through the door. However, the overall temperature will also depend on the garage’s walls, roof, floor, ventilation and any gaps around the opening.

The cost depends on the opening size, door specification, colour, fitting requirements and optional extras. If you are converting two entrances into one, any structural work will also affect your overall budget.
