Formula breakdown
Formula
ch = round(width × (gauge ÷ 10)) + turning chains= 1.8
Note
Simplified model: these are standard craft estimates based on rectangular layouts, quoted gauge and nominal densities. Real fabric nap, directional prints, shrinkage, pattern matching, yarn lots and supplier SAP values vary, so always make a swatch or test piece and buy a little extra.

Why is my starting chain always a bit different from the pattern's flat foundation length?+
Chain stitches vary in tightness from crocheter to crocheter more than most other stitches, so the same stitch count can produce different lengths depending on tension. This calculator uses your own gauge (chains per inch) to convert a target length into the right number of chains for you specifically.
Do I need to add extra chains beyond the calculated number?+
Many patterns recommend one or two extra turning chains at the start, which don't count as working stitches in the first row; check whether the pattern's row 1 instructions skip a chain or two before working the first stitch.
Why does my finished foundation row look shorter than my starting chain?+
Working stitches into a chain, especially double or treble crochet, pulls the chain slightly tighter and shortens the row versus its unworked length. If foundation length matters exactly, measure gauge on a worked swatch, not on an unworked chain.
How is chain gauge different from stitch gauge?+
Chain gauge measures how many chain stitches fit in an inch of unworked chain, while stitch gauge measures worked stitches (like single or double crochet) per inch; the two numbers are usually different because chain stitches are simpler and often looser.
What's a foundation chain used for beyond starting a project?+
Beyond starting flat pieces, chain length calculations are used for ties, straps, drawstrings, and edging trims where you need a chain of a specific finished length rather than a specific stitch count.
