How to Measure Windows and Doors Information

MEASURE WINDOWS AND DOORS


Standard Windows Or Doors

Measure the height of the opening in the brickwork from outside and check this dimension in 3 or 4 points across the frame.  Use the smallest dimension and from this deduct 6mm (1/4″) to find the height of the frame you require.  Measure the width of the opening in the brickwork (ensuring that your measuring tape is level) and check this dimension 3 or 4 times up the opening and use the smallest measurement.  Deduct 10mm if you are using pvc-u windows or 6mm if you are using aluminium or wood from this measurement to find the width of the frame you require.

If you have render on the outside of the property, you will note that the window is fitted behind this.  It will be necessary to remove the external render around the opening to fit the new window or door and the frame measurement will need to be carefully measured as above.

IMPORTANT: Where windows are fitted directly below soffit boards side hung openings can be obstructed by the fascia.  Measure the distance the fascia board drops below the soffit and if this is more than 20mm (3/4″) please advise us and we will ensure that we design the window to ensure it opens fully.
