Guides: how much fabric do you need?
Charts and rules of thumb get you close, and every guide here gives you those first, with their fine print. The exact number always comes from laying your actual pattern pieces onto your actual fabric width. That part is what PatternNest automates, and the free tier covers most of these projects.
How much fabric do I need?
The chart, its fine print, and two ways to an exact number.
Circle skirt
The formula, the table, and the width cliff at 60 cm length.
Dress
Why serious answers span 1.5 to 4 metres, and what moves them.
Skirt
One skirt length or two? The rule and its breaking points.
Pants
The two-leg width test that decides between 1.3 and 2.3 m.
Hoodie
Hood, pocket, ribbing: the pieces that blow the estimate.
Cape or cloak
3 to 10 yards is not a typo: semi vs full circle, hood, lining.
45 vs 60 inch conversion
Area-ratio charts work until one piece stops fitting.
One-way prints and nap
The quoted 15 to 25 percent extra, and the real penalty.
Not enough fabric?
