Before you start

How wide?

First, measure the top, middle and bottom of the frame opening where the door will go. Use the widest measurement to find the width of your new door.

How high?

Again, measure in three points (this time to the left, centre and right) within the frame opening where the door will be. The longest length will tell you the height of your new door.

Any adjustments?

When you've taken your measurements, compare them with the sizes available in the style you like. While you're choosing, remember that different doors allow different amounts of trimming so if you can't buy the exact size, make sure you check the amount you can trim so that you can achieve the perfect fit.
