Working out how much fabric to get for your project can be a bit confusing. But don't worry, we've got you covered. Here's an easy way to calculate it:
Before you start ripping off the old fabric, grab a tape measure, pen, and paper.
Measure each fabric panel, and don't forget to add 1.5cm for each sewn edge and 5cm for each stapled edge.
Plot everything onto your fabric graph (you can download a free graph).
If you're using piping, make sure to add piping fabric to your graph. The standard fabric width for piping is 4.5cm.
Once you've plotted everything, the graph will give you an idea of how much fabric you need.
Pro tip: It's always better to add a little extra fabric for patterns, stripes, napped fabric, flaws, or errors. Better safe than sorry!
