Measuring for Wooden Garage Doors

CDC Garage Doors supply and install wooden garage doors that bring style and sophistication to your home. Working with a number of manufacturers, we can help you find the perfect door for your needs. But it’s important to know how to measure properly to make sure that the door is the right size. You can benefit from our years of experience – read on for advice and guidance.

To measure for your new wooden doors correctly it’s actually more important to know the manufacturer and the type of door that you’re going with. The majority of wooden doors are either up-and-over or sectional, and you’ll need to measure differently depending on the one you choose.

For up and over wooden garage doors

When buying a wooden door that is going to be fit into an existing frame (or if you’re replacing your current frame with one of the same dimensions) you simply need to measure the height and width within the frame. Note that it can sometimes be more cost-effective and faster to change the frame so that you can order in a standard size.

Alternatively if you are installing a door inside a structural opening you should measure the height and width of the opening. Make sure you measure in multiple places and use the smallest measurement. Manufacturers will also need the smallest reveal on both sides of the opening and the headroom measurement, again, taking the smallest available measurement.

When buying a door that is going to fit in-between a structural opening you usually only need to supply the width and height of the opening, but you should always check with the manufacturer.

For sectional wooden garage doors

Ordering sectional garage doors varies significantly by manufacturer. When you measure for a door that is going inside a structural opening you usually need to take the width of the opening and add 90mm to each side. For the height you will need to find out the manufacturer’s specific requirements.

It’s different for a door that’s being fitted in-between the opening. Here you need to measure the height and width of the opening as well as the depth of your garage.
