How the Finished Crochet Size Calculator Works

The Finished Crochet Size Calculator works in 4 steps.

1
Enter the total planned stitches
Type the stitches per row from the pattern, such as 120.
2
Enter the total planned rows
Type the rows in the pattern, such as 150.
3
Enter your gauge
Type your stitches and rows per 4 inches (10 cm) from a blocked swatch.
4
Press Calculate Result
Read the finished width and length in inches and centimeters.

Finished Crochet Size Calculator Formula

The Finished Crochet Size Calculator formula divides each count by its gauge and multiplies by the 4-inch base.

Width = (Total stitches ÷ Stitch gauge) × 4

Length = (Total rows ÷ Row gauge) × 4

Total stitches: Stitches per row
Total rows: Rows in the piece
Stitch gauge: Stitches per 4 inches (10 cm)
Row gauge: Rows per 4 inches (10 cm)

Worked example: 120 stitches and 150 rows at 16 stitches and 12 rows per 4 inches: width = (120 ÷ 16) × 4 = 30 inches (76.2 cm), and length = (150 ÷ 12) × 4 = 50 inches (127 cm).

Finished Crochet Size Calculator Conversion Table

The Finished Crochet Size Calculator conversion table shows finished sizes for common stitch and row counts at 16 stitches and 12 rows per 4 inches (10 cm).

Stitches × rows	Width (in)	Width (cm)	Length (in)	Length (cm)
24 × 24	6	15.2	8	20.3
40 × 60	10	25.4	20	50.8
80 × 90	20	50.8	30	76.2
120 × 150	30	76.2	50	127
140 × 180	35	88.9	60	152.4
200 × 240	50	127	80	203.2

Width uses 4 stitches per inch and length uses 3 rows per inch at this gauge.

What is a Finished Crochet Size Calculator?

A finished crochet size calculator is a calculator that predicts the width and length of a piece from its stitch count, row count and gauge. The Crochet Stitch Counter Finished Crochet Size Calculator shows the final dimensions before you crochet the first row.

Patterns list stitch and row counts. Your gauge converts those counts into inches and centimeters. When your gauge differs from the pattern gauge, the finished size changes, and this calculator shows by how much.

Checking size before starting saves hours of work on a piece that ends up too small or too large.

What are the Uses of a Finished Crochet Size Calculator?
