How many extra stitches do cables add?

Each cable panel needs the cable stitches themselves (e.g. 6 for a C6F) plus border stitches either side (typically 2 purl stitches per side). A 6-stitch cable with borders adds 10 stitches per panel. Two cable panels would add 20 extra stitches to your cast-on count.

How do cables affect width?

Cables pull the fabric in because the crossing stitches compress horizontally. A cable panel is typically 10-20% narrower than the same number of stitches in stockinette. This means you need to add extra stitches to maintain the same finished width.

How often do I cross the cable?

The standard rule is to cross a cable every N rows where N equals the number of stitches in the cable. A 6-stitch cable crosses every 6 rows. Some patterns modify this — crossing more frequently creates a tighter twist, less frequently gives a more relaxed rope effect.

Do cables use more yarn?

Yes, cables use approximately 10-15% more yarn than stockinette because the crossed stitches travel diagonally rather than straight up. The wider the cable and the more frequent the crosses, the more extra yarn is needed. Factor this into your yarn estimate.

How We Calculate This

This calculator works out the extra stitches needed when adding cable panels to a pattern, accounts for the width pull-in caused by cables, and estimates extra yarn usage.

Stitch calculation

Extra stitches = (Cable width x Number of cables) + Border stitches

Width adjustment

Width pull-in = Cable panel width x Pull-in percentage (default 15%)

Cable crossing

Cross every N rows = Cable stitch count x 2
