For a more accurate count, please bring along your room measurements into store and our staff will be able to offer you a much more accurate count based on your chosen pattern.

A little extra help…

A standard door measures approximately 0.8 m x 2.0 m or 1.6 sq m (2 ft 7" x 6 gt 6" or 20 sq ft).

A standard window is about 0.9 m x 1.2 m or 1.1sq m (3 ft x 4 ft or 12 sq ft).

The calculator provides your estimate based on a standard UK/EU rolls coverage approximately 10.05m long (11 yards / 33 feet) and 530mm (21”) wide, excluding all matching.

It is recommended that you purchase sufficient rolls for the job in hand as repeat sales cannot be guaranteed.
