Remember: Measure Twice, Order Once!

There are a few key things to consider to help you avoid ordering the wrong sized garage door. Firstly, if you are replacing your existing up and over garage door, you must choose whether you are going to retain your existing wooden frame or whether you would prefer your new garage door to be supplied complete with a lower maintenance steel or GRP factory frame (recommended) that will fix directly to your brickwork. To help you get the correct measurements please download our Standard Garage Door Sizes chart.

Standard Garage Door Sizes

If you are going to retain your existing timber frame, measure the internal dimensions of the frame. Make sure the frame is sound, square and securely fixed to the brickwork, look out for signs of rotting at the bottom of the frame leg. Also ensure that the timber is the recommended minimum size of 75mm x 75mm (3" x 3"). Always measure the width and the height of the aperture from more than one point as the brickwork or timber frame may not be consistent.

If you would like your new garage door to come with the recommended factory frame, measure the brickwork to brickwork width of your opening. To determine the height of your garage opening, measure from the floor to the underside of the lintel.

The ordering size of your new garage door does not allow for any fitting tolerances, such as uneven brickwork or floor finishes. You will need to allow for any tolerances when ordering your door by taking the measurement across the opening in at least 3 separate places, i.e. top, middle and bottom, you will need to work to the smallest width taken. Do the same again for the height by taking measurements a the left, centre and right. Please double check all your measurements.

Traditionally most Garage Door openings in the UK are built to imperial measurements (feet & inches) and most standard garage door sizes are therefore manufactured to imperial dimensions. If you are constructing a new garage we can supply made to measure doors or standard metric sizes for certain door styles.

All garage door sizes shown on www.GarageDoorSuperstore.co.uk are nominal, the size stated refers to the size of the opening through which the garage door travels i.e. internal frame size. The manufacturer will make a deduction to provide the necessary clearance and the true size for the door itself may be smaller. Because of this deduction, always measure your opening size and not the size of your existing door panel. Once you have established the dimensions of your garage door opening you must consider the internal dimensions of your garage to ensure that the track & mechanism will fit. The length of any ceiling mounted tracks will generally depend on the height of the door. The track for electric openers can extend up to 1500mm beyond the open door.
