How to Measure Garage Doors

Looking to replace your old domestic or commercial garage door with a new door? But your garage isn’t the standard garage door size? NZ garages vary in dimension combinations, so determining the correct configurations can be challenging. 

At Doors NZ, we sell a variety of door styles in pre-painted steel, aluminium and timber. You don’t need to worry about standard door height in NZ because we manufacture different garage door sizes at great prices to suit your home or business.

To get started:

  1. Visit our Commercial Roller Doors, Domestic Roller Doors,  Semi-Industrial Roller Doors or Sectional Garage Doors pages to find the right door style suited to your building.
  2. Measure the height of the lintel of your garage door in millimetres.
  3. Measure the opening width – between the finished trimmers.
  4. Round up if necessary, as we will manufacture to the exact dimensions.
  5. Choose your options – work your way down the page selecting the level of supply and service you prefer.

NOTE: We do not come to your site and measure and quote. However, we can usually quote from your measurements and photos.

Note:

All roller garage doors are measured to daylight opening dimensions (door opening height x width – see the below diagram). We will ask you for these dimensions. The curtain will be wider - between 50mm and 115mm. We will order per this measurement.
Opening Size
Recommended clearance requirements for installation:

Standard Headroom with opener - Dominator/Garador: 350mm.

Low Headroom with opener - Dominator/Garador: 200mm.

Sideroom with opener  - Dominator: 135mm on both sides. Garador 140mm.

Backspace with opener - Dominator/Garador: 3550mm (door height up to 2300mm)

Dominator and Garador use 25mm guides as the default guide size, making the curtain 50mm bigger to overlap. Windsor Doors use 40mm guides, and the curtain is 70mm larger.

If you do not see your roller door size, simply round up. You can advise your precise dimensions at a later stage.
