Letterbox measuring guide showing how to measure cut-out width, cut-out height, and door thickness for a uPVC or composite front door

Not sure if this letterbox will fit your door?

Before ordering, take three measurements from your existing letterbox opening. If all three match the dimensions listed above, this letterbox will fit your door perfectly.

Cut-out width
Measure the full horizontal length of the opening in your door from edge to edge. This is the most common size to match — typical UK letterboxes are between 250mm and 300mm wide.

Cut-out height
Measure the vertical height of the opening from top to bottom. Most UK letterbox cut-outs are between 40mm and 75mm high.

Door thickness
Measure the thickness of your door from front face to back face. UK uPVC and composite doors are typically 44mm or 70mm thick.

Got all three? You're good to go.

Still unsure? Send a photo of your existing letterbox to info@homesecureshop.co.uk and we'll match it for you — or call 0151 521 8089 to speak to our team.
