How do crochet stitch heights compare?

Each stitch type has a different height. Using dc (UK) as the baseline: htr is approximately 1.5x taller, tr is 2x taller, dtr is 2.5x taller, and trtr is 3x taller. These ratios are approximate and vary with individual tension.

Why does stitch height matter?

Stitch height determines your row gauge and how quickly your work grows in length. Taller stitches mean fewer rows for the same length, which makes projects faster. However, taller stitches also create more open fabric.

How do I measure my dc row height?

Make a dc swatch of at least 10 rows. Measure the total height and divide by the number of rows. For example, 10 dc rows measuring 8cm means each dc row is 0.8cm tall. Use this as your baseline measurement.

Does yarn weight affect stitch height?

Yes. Thicker yarn produces taller stitches. The height ratios between stitch types remain roughly the same, but absolute heights increase with yarn weight. Always measure your own gauge rather than relying on generic values.

What about mixed-stitch patterns?

For patterns that combine stitch types (e.g. a row of dc followed by a row of tr), calculate the height of each row type separately and add them together. This calculator helps you determine individual row heights for planning.

How We Calculate This

This calculator uses your dc (UK) / sc (US) row height as a baseline, then applies standard height ratios for taller crochet stitches.

Stitch height ratios

DC (UK) / SC (US): 1.0x (baseline)
HTR (UK) / HDC (US): 1.5x
TR (UK) / DC (US): 2.0x
DTR (UK) / TR (US): 2.5x
TRTR (UK) / DTR (US): 3.0x

Row height = DC row height x Stitch ratio

Rows needed = Target length / Row height
