Crochet Circle Round Planner
Generate a basic staggered-increase circle schedule from a selected stitch preset and round limit; swatch and adjust for the material and stitch.
A bounded arithmetic planner for one of four common crochet starting-count presets: 6, 8, 12, or 16 additions per later round.
Crocheters who want a count-preserving starting schedule to compare with a selected pattern and the actual fabric.
The planner does not accept gauge or target diameter and cannot guarantee flatness, roundness, fit, or finished size.
8 rounds selected; ending count 48; 6 preset additions per round.

Reference round schedule
Round 1: Place 6 sc in the selected center start. (6 sc)
Round 2: 2 sc in each st around. (12 sc)
Round 3: *2 sc in next st, sc in next 1 st* repeat 6 times. (18 sc)
Round 4: *sc in next 1 st, 2 sc in next st, sc in next 1 st* repeat 6 times. (24 sc)
Round 5: *sc in next 3 sts, 2 sc in next st* repeat 6 times. (30 sc)
Round 6: *sc in next 2 sts, 2 sc in next st, sc in next 2 sts* repeat 6 times. (36 sc)
Round 7: *2 sc in next st, sc in next 5 sts* repeat 6 times. (42 sc)
Round 8: *sc in next 3 sts, 2 sc in next st, sc in next 3 sts* repeat 6 times. (48 sc)
Check the actual fabric
Yarn, hook, tension, stitch dimensions, joins, and chain-counting conventions can change the shape. Compare each round with the selected pattern and adjust from observed cupping or rippling instead of treating a preset as a flatness guarantee.
Formula and calculation method
For selected preset p, round 1 ends with p stitches and round r ends with p × r stitches. Every later round therefore adds p stitches.
At round r, each of p repeats consumes r − 1 prior stitches: one stitch receives an increase and r − 2 remain plain. The repeats consume p × (r − 1) stitches, exactly the prior-round count.
The displayed arrangement alternates increase placement as a counting aid. It does not calculate physical curvature or establish a finished diameter.
Worked example
Choose the single-crochet 6 preset and 6 rounds. The schedule starts with 6 stitches in round 1 and adds 6 stitches per later round, so round 6 ends with 36 stitches. That verifies the selected arithmetic only; compare the actual fabric and selected pattern before continuing.
Assumptions and limitations
- !The generated increase schedule is a starting plan, not a guarantee that every yarn, hook, and tension combination will lie flat.
- !A circle that cups or ripples should be checked against the actual fabric before adding rounds; hook size, stitch height, and personal tension can require adjustment.
- !The selected round count controls the written pattern length, not a fixed finished diameter. Measure the work at your own gauge.

Frequently Asked Questions
What do the 6, 8, 12, and 16 options mean?
They are common starting-count presets used by this arithmetic reference. They are not universal flatness rules for every yarn, hook, stitch, tension, or join.
Does the schedule guarantee a flat or round circle?
No. It preserves the selected count progression only. Check each round against the selected pattern and the actual fabric, then adjust deliberately if it cups or ripples.
Does the planner calculate diameter or accept gauge?
No. It accepts only a preset and a round limit. It does not predict finished diameter, project size, fit, or yarn use.
Does it choose a magic ring, join, or turning-chain convention?
No. Use the center start and round convention required by the selected pattern, including whether chains count as stitches.
