Knitting & crochet calculator
Project Time Estimator
Estimate how many hours and calendar weeks a knitting or crochet project may take from total stitches, pace, and weekly crafting time.
Project time is mostly a pace calculation: total stitches divided by stitches per minute. The hard part is estimating the total stitch count and remembering that finishing work also takes time.
This calculator converts total stitches into stitching hours, adds a finishing buffer for blocking, seaming, weaving ends, and corrections, then divides by your available crafting hours per week. It is best for comparing projects or setting expectations, not for predicting an exact finish date.
Worked example: 12,000 stitches at 20 stitches per minute is 600 minutes, or 10 hours of stitching. With a 10% finishing buffer and 5 available hours per week, the project takes about 2.2 weeks.
Frequently Asked Questions
How do I estimate total stitches?
For a simple rectangle, multiply stitches per row by the number of rows. For shaped garments or motifs, estimate each section separately and add them together.
What pace should I enter?
Time yourself for 5 to 10 minutes in the actual stitch pattern, then divide stitches completed by minutes worked. Complex cables, lace, colorwork, and textured crochet will be slower.
What does the finishing buffer include?
It covers non-stitching work such as weaving ends, seaming, blocking, attaching pieces, checking fit, and fixing small mistakes.
Why is this only an estimate?
Real projects include interruptions, mistakes, gauge changes, fatigue, and sections that work faster or slower than the sample pace.
