Measuring up, what size of door do I order and will it fit into my
garage?
Having reviewed the characteristics of the different door types and
decided what is best for you it is time to work out what size of door
you require so that we can give you an accurate quotation.
Read through the information below, decide what you need to
measure and grab a tape measure, pen and paper and head off to your
garage.

Prior to confirming your order we will supply you with the exact
space and clearance information for your door to double check that it is
suitable.
1.
Retractable, Canopy and Side Hinge doors - fitting
to an existing frame
a. Measuring up:
If your frame already exists, please make
sure that:
-
The frame is structurally sound
and in good condition
-
The frame is securely fixed to
your garage structure
-
Side frames are upright and
parallel
-
The top of the frame is level and
square to the sides
If your frame is not
up to scratch you have a couple of options: Replace
it with a new timber frame, or, replace it with a
Plastisol-treated steel frame that can be pre-fitted
to your door.
To identify the size of door that you need simply
measure the dimensions in the following diagram.
Check the dimensions at various points to ensure
consistency and verify the diagonal dimensions to
ensure the frame is square (the two dimensions
should be the same… not as shown).
 
Door sizes are always quoted
WIDTH x HEIGHT and are sold to fit the opening
size, i.e. a 7' x 6'6" door will actually be
slightly smaller so that it fits into a 7' x
6'6" opening with the necessary clearances.
b. Will it fit? Door
space constraints:
Retractable: The full height of the
door slides back into the ceiling of the garage
when opened.
Canopy: As one-third of the door
protrudes outside of the garage less space is
needed to 'store' the open door.
Dimensions: A (depth into garage) and
B (additional height above underside of door
frame) vary with each
manufacturer and door type as follows:
2. Retractable and Canopy doors -
pre-framed
a. Measuring up:
If you wish to replace your existing frame or
simply fit a pre-framed door to your existing
brick opening you can identify the size of door
that you need by simply measuring the dimensions
in the following diagram. Check the dimensions
at various points to ensure consistency and
verify the diagonal dimensions to ensure the
frame is square (the two dimensions should be
the same).
Door sizes are always quoted WIDTH x HEIGHT
and are sold to fit the opening size, i.e. a 7'
x 6'6" door will actually be slightly smaller so
that it fits into a 7' x 6'6" opening with the
necessary clearances.
Pre-framed doors may be mounted within the
opening or mounted on the rear face of the
garage structure to give a little more
flexibility. If mounted to the rear face a
frame to brick overlap of approximately 50mm is
required.
b. Will it fit? Door space constraints:
See previous section.
3. Sectional and Roller Doors
a. Measuring up:
Sectional and Roller doors are mounted to the
rear face of the garage structure and do not
require a frame. To identify the size of door
that you need simply measure the dimensions in
the diagram below - the opening does not have to
be true or square - you can even have an arched
opening.
Door sizes are always quoted WIDTH x HEIGHT
and are sold to be bigger than the opening size,
i.e. a 7' x 6'6" door will actually be
approximately 180mm wider and 100mm higher so
that it fits around a 7' x 6'6" opening.
b. Will it fit? Door space constraints:
Clearance is required on either side and above
the rear face of the opening.
