It helps to think in terms of the number of

**linear metres**required to cover an area of 1 square**metre**, (1m x 1m). To**calculate**this, first assume that the 1m 'length' of the area is always covered by 1m long decking boards. Then, establish how many boards need to be laid side by side to cover the areas 1m 'width'.Then, what is a lineal meter?

A

**lineal metre**is a**metre**at whatever width the product is produced at. And with roofing metal you also need to allow for an overlap. Do you know the width of each sheet and the length of your roof? Edited by dadathome, 25 March 2013 - 02:15 PM. Back to top.How long is a roll of carpet?

Carpet is produced in large rolls that come in fixed widths. Possibilities for roll widths are

**12 feet, 15 feet**, and**13 feet 6 inches**, in order of availability. Unlike the width, the length can be any number; carpet is rolled out and cut at the desired length.How do you work out how much carpet you need?

To calculate your total square footage for a room, just multiply your room width and length together. Here is what a 10 x 10 room would add up to 13.33 yards: (Remember,

**carpet**comes 12 feet wide) That is 12' width x 10' length = 120 square feet divided by 9 = 13.33 yards.
