Adding a door canopy is one of the simplest ways to enhance your home. It boosts kerb appeal, protects your doorway, and keeps you dry in the unpredictable UK weather. But one of the first questions most people ask is: what size canopy do I need?

This guide covers standard canopy sizes, projections, and measurements, plus tips on making sure your chosen canopy fits perfectly.


What’s the Average UK Front Door Size?

Most UK front doors measure around 1981mm tall by 762mm wide (6’6” x 2’6”).

  • Modern homes may have slightly wider doors (up to 838mm).

  • Older or cottage-style homes are often narrower.

Grab a tape measure before ordering — it’s the only way to be sure.

Standard Door Canopy Sizes

Door canopies come in a variety of widths, but the most common are:

  • 1000mm wide – Best for narrow entrances.

  • 1200mm wide – The most popular size for standard UK doors.

  • 1400mm wide – Works well for wider doors or when you want extra coverage.

  • 1800mm+ wide – Ideal for double doors or a grander statement look.

Projection (depth): Most canopies project between 600mm–800mm, which provides good everyday shelter.


Choosing the Right Canopy Size

The right canopy size depends on more than just the width of your door:

✔ Coverage – Extend 100–200mm wider than your door frame.

✔ Proportion – Avoid canopies that look too small or oversized.

✔ Style – Apex canopies need more vertical clearance, flat canopies less.


How Far Should a Door Canopy Project?

Projection = how far the canopy extends from the wall.

  • 600mm = sufficient for lighter rain.

  • 800–1000mm = better for full protection in heavy rain.

⚠️ To stay within permitted development rules, canopies should project less than 1 metre from the wall.


How to Measure for a Door Canopy

  1. Measure door width (including frame).– Add at least 100mm each side for proper coverage.

  2. Check vertical clearance.– Apex canopies need more height (min 835mm). Flat canopies need less (min 250–293mm depending on style).

  3. Decide on projection.– Standard: 600–800mm. More if you want parcels and guests fully sheltered.

  4. Account for brackets.– Gallows brackets need wall space either side of the frame.

  5. Take notes and photos.– Useful when comparing designs or seeking advice.
