Frequently asked questions
How big is a roll?
A common roll is 0.53 m wide by 10 m long, about 5.3 m² (57 sq ft). There are also 0.52 × 10 m rolls, wide 1.06 m rolls and, in the US, double rolls of about 56 sq ft. Check the label.
What is the pattern repeat?
It is the vertical distance at which the pattern repeats. To line up the design from one strip to the next, each strip has to be cut a bit longer, which increases usage.
Should I buy an extra roll?
It's recommended. Rolls from different batches can differ slightly in color, so buy everything at once, with one spare roll for repairs.
