Blanket Drape Secret: Blankets made with double crochet (dc) or moss stitch have much softer drape and fold nicely over arms or beds compared to single crochet (sc), which creates a stiff, cardboard-like fabric unless worked with a hook 2-3 sizes larger than recommended.
How to use the scarf size calculator
- Row 1Enter your scarf's finished width and length in the custom size fields. A scarf is simply a long rectangle.
- Row 2Choose your yarn weight and your stitch.
- Row 3Read the starting stitches, rows, estimated yardage and skeins.
- Row 4Adjust the width or length until the yarn amount fits your budget or your stash.
Common scarf sizes
Scarf sizes aren't standardized, but these are typical starting points:
| Style | Width | Length |
|---|---|---|
| Child scarf | 4–6 in (10–15 cm) | 36–48 in (90–120 cm) |
| Adult scarf | 6–8 in (15–20 cm) | 60–72 in (150–180 cm) |
| Long wrap scarf | 8–10 in (20–25 cm) | 72–80 in (180–200 cm) |
| Infinity scarf (joined loop) | 8–12 in (20–30 cm) | 50–60 in (125–150 cm) around |
| Cowl (close-fitting loop) | 8–12 in (20–30 cm) | 22–28 in (55–70 cm) around |
A good test for length: a classic scarf is often about as long as the wearer is tall, minus a little. For a cowl, measure around the wearer's head, since it has to pull on over it.
Worked example
An adult scarf 8 × 70 inches in worsted and double crochet:
- At a typical 3.5 stitches per inch: 8 × 3.5 = 28 stitches across
- At 2.2 rows per inch: 70 × 2.2 = 154 rows
- Yardage: 8 × 70 = 560 square inches × 0.75 = about 420 yards
- Skeins: about 3 typical 200-yard balls
Fringe adds extra: each tassel uses several strands of a few inches each, so add 50 to 100 yards for a fringed scarf.
Scarves worked lengthwise
Some scarves are worked lengthwise: you chain the full length and work rows across it. This makes long stripes and finishes quickly in terms of rows, but the foundation chain is very long. Enter the dimensions the same way; the yardage is the same either way. Use the chain calculator to count the foundation chain, or try foundation single crochet to skip it.
The formula
Stitches = width × typical stitches per inch. Rows = length × typical rows per inch. Yardage = width × length × yards per sq in for the yarn weight × stitch factor. Skeins = yardage ÷ typical yards per 100 g ball.
Tips
- Half double crochet and the moss stitch make warm scarves with nice drape.
- Block the finished scarf to straighten the edges and set the length.
- Stretchy stitches can grow when worn, so err on the shorter side for heavy yarns.
- Joining the ends of a scarf? Add a twist before joining for a Möbius-style infinity scarf.
