The structural opening width and height is the size of the gap any persons/ objects can pass through freely when the door is opened fully. However, the effective clear opening width takes into consideration the ironmongery/hardware on your door.

When sizing up your door you should always measure the width and height from at least 3 different points within the aperture. Sometimes you may find your structural opening is not perfectly square. The width at the top and bottom may differ slightly, or the height may vary from one side to another. If this is the case, you should quote the smallest measurements. If there is a significant difference, please inform the sales team when requesting a quote. At Bluseal, we will take your structural opening size and remove the tolerance in house. When requesting a quotation from us, you must always state the structural opening size only and never take the tolerance off yourself.

When replacing an existing door, you must always request a quotation using the structural opening size only. You should never use the measurements of the existing door that is already installed as this is not an accurate and reliable measurement. If the previous door you are replacing is a Bluseal door, you can provide the serial number to our sales team who will be able to advise the previous sizing, you can locate this in the jamb of the door.

Here’s how to work it out for a single door:

1. Stand on the side where you pull the door towards you.
2. Open the door.
3. Look at which side the hinges are on.
   • Hinges on the left = Left-Hand Door.
   • Hinges on the right = Right-Hand Door.
