Crochet Size Chart for Gifts: Hats, Mittens, Scarves and Blankets
Quick answer: For hats and mittens, use the Craft Yarn Council body measurements. For scarves and blankets there is no industry standard, so size them from the person or the bed.
- Hat, adult woman: head 21 to 23 in · adult man: 22 to 24 in
- Hat, child: head 18 to 20 in · toddler: 16 to 18 in
- Mittens, woman medium: hand 7½ in around, 6½ in long
- Mittens, man medium: hand 8½ in around, 7¾ in long
- Scarf and blanket: measure, then add (worksheet below)

Crochet gifts usually go to someone you cannot measure without spoiling the surprise. This page gives you the published body measurements for the two gifts that have them (hats and mittens), and a simple measure-and-add method for the two that do not (scarves and blankets). Every number in the hat and mitten tables comes from the Craft Yarn Council, the US yarn industry group that publishes the standard yarn weights and hook sizes. The worksheet math is ours.
Which gifts have a published size standard?
| Gift | Key measurement | Craft Yarn Council chart? | What to use |
|---|---|---|---|
| Hat or beanie | Head circumference | Yes, by age group | Hat table below |
| Mittens | Hand circumference and hand length | Yes, child, woman and man | Mitten table below |
| Scarf or cowl | Wearer and style | No | Measure on a scarf they already wear |
| Blanket or throw | Bed top or the person | No | Measure-and-add worksheet |
Based on the Craft Yarn Council's Standard Body Measurements/Sizing index, checked October 27, 2026, which lists baby, child/youth, woman, man, head circumference, foot and hand charts, and no scarf or blanket chart.
Hat sizes by age (head circumference)
Measure around the head, not the hat. A hat pattern tells you which head size each version fits, and this table tells you which head size to pick when you cannot measure.
| Size group | Head (in) | Head (cm) |
|---|---|---|
| Preemie | 9 to 12 | 23 to 30.5 |
| Baby | 14 to 16 | 35.5 to 40.5 |
| Toddler | 16 to 18 | 40.5 to 46 |
| Child | 18 to 20 | 45.5 to 51 |
| Tween | 20 to 22 | 51 to 56 |
| Woman | 21 to 23 | 53 to 58.5 |
| Man | 22 to 24 | 56 to 61 |
Source: Craft Yarn Council, Head Circumference Chart, checked October 27, 2026 (as of October 2026). The chart gives ranges only; it does not list hat heights or exact ages for each group.
The groups overlap at the edges (a 16-inch head is both the top of Baby and the bottom of Toddler), and adult ranges overlap by a full inch. When you are guessing, pick the middle of the range. For hat height, stitch counts and baby sizing notes, see our crochet hat size chart by age.
Mitten sizes (hand circumference and length)
| Size | Hand around (in) | Hand around (cm) | Hand length (in) | Hand length (cm) |
|---|---|---|---|---|
| Child 2 to 4 years | 5 | 13 | 4 | 10 |
| Child 4 to 6 years | 6 | 15 | 4¾ | 12 |
| Child 6 to 8 years | 6½ | 16.5 | 5¼ | 13.5 |
| Woman small | 7 | 18 | 6 | 16 |
| Woman medium | 7½ | 19 | 6½ | 16.5 |
| Woman large | 8 | 20.5 | 7½ | 19 |
| Man small | 8 | 20.5 | 7½ | 19 |
| Man medium | 8½ | 21.5 | 7¾ | 20 |
| Man large | 9 | 23.5 | 8½ | 21.5 |
Source: Craft Yarn Council, Hand Size Charts, checked October 27, 2026 (as of October 2026). We turned the three source tables (child, woman, man) into one. The centimeter values are the Council's own rounded figures, so a few do not convert exactly from the inches. The Council does not list thumb or finger lengths.
Notice that a woman's large and a man's small share the same numbers. If you are making mittens for an adult and do not know the hand size, a woman's medium or a man's medium is the middle of each range. For stitch counts and a glove worksheet, see our crochet mitten size chart by age.
Scarves: size from the wearer, not a chart
The Craft Yarn Council does not publish scarf sizes, and scarf length is mostly a style choice. The most reliable measurement is one you can take secretly: borrow a scarf the person already wears and likes, lay it flat, and measure its length and width. If that is not possible, use the table below to decide what to measure on yourself as a stand-in.
| Style | Measure | Tip |
|---|---|---|
| Wrap once, ends hanging | Tape around the neck once, then down to where the ends should stop, on both sides | Add any fringe length separately |
| Wrap twice | Same as above with two loops around the neck | Bulky yarn uses up length fast in the loops |
| Cowl (closed loop) | Around the neck loosely, or around the head if it must pull over | Pulls over the head? It must be larger than head circumference |
| Child's scarf | A scarf the child wears now, or a parent's estimate | Shorter ends are easier for small children to manage |
Our own guidance. No primary source publishes scarf dimensions. For example lengths worked out from body measurements, see our crochet scarf size chart for kids and adults.
Blankets: the measure-and-add worksheet
Blanket sizes are not standardized either, and mattress sizes vary by brand. So instead of a chart, use the bed or the person in front of you:
Diagram and formula by our team.
| Step | Example input or calculation | Result |
|---|---|---|
| 1. Measure the mattress top | Example only: 38 in wide, 74 in long (use your tape measure) | W = 38, L = 74 |
| 2. Choose a drop | Example: 10 in down each side and at the foot | D = 10 |
| 3. Width | 38 + 2 × 10 | 58 in |
| 4. Length | 74 + 10 | 84 in |
| 5. Turn width into stitches | 58 in × your gauge. Example gauge: 12 sc per 4 in = 3 sc per in, so 58 × 3 | 174 stitches |
We calculated these figures ourselves. The mattress size and drop are example inputs, not standard sizes. The example gauge of 12 sc per 4 inches sits inside the Craft Yarn Council's 11 to 14 sc range for Medium (4) worsted yarn, checked October 27, 2026; use the gauge from your own swatch.
For a throw or lap blanket, skip the bed: have someone sit on the couch where the blanket will live and measure from their shoulders to their feet, and across the width they would want covered. For a baby gift, see the safety note below before you choose a size. For bed sizes and stitch counts, see our crochet blanket sizes chart.
Baby blankets: a safety note
A crocheted baby blanket makes a lovely gift for the stroller, a play mat or a keepsake, but not for the crib. The NIH Safe to Sleep campaign lists blankets, quilts and comforters, along with pillows, stuffed toys and bumpers, among the items to keep out of a baby's sleep area, and says keeping them out is the best way to avoid the dangers they pose (Safe to Sleep: safe sleep environment, checked October 27, 2026). This is general information, not medical advice; talk to your child's doctor with questions about safe sleep. A gift tag that says "for supervised awake time" is a kind way to pass this on.
Guessing a size when you cannot measure
- Hats: pick the Craft Yarn Council group for the person's age and aim for the middle of its range. A teen or small adult often sits in the Tween or Woman range, which overlap at 21 to 22 inches.
- Mittens: medium is the middle of the woman and man charts. For a child, go by the age band and round up if they are between bands, since hands grow.
- Scarves: a scarf can be a little long or short and still work, which makes it the safest surprise gift.
- Blankets: a throw sized for a couch works for nearly anyone. Bed blankets need the real mattress measurement.
- Care: tuck the yarn label in the gift box, so the recipient has the fiber and care instructions.
Common sizing mistakes
- Measuring an old hat instead of the head. Hats stretch, so a worn hat can read larger than the head it fits.
- Skipping the gauge swatch. A size chart only helps if your stitches match the pattern's gauge. Our crochet hook sizes chart lists the Craft Yarn Council's gauge range for each yarn weight.
- Following a UK pattern with US stitch names. Every stitch comes out taller, and the whole gift comes out bigger. Check our US vs UK crochet terms chart first.
- Assuming "baby" means one size. The Craft Yarn Council's Baby, Toddler and Preemie hat groups span 9 to 18 inches between them.
FAQ
What size should a crochet hat be for an adult woman?
The Craft Yarn Council lists an adult woman's head as 21 to 23 inches (53 to 58.5 cm) around. If you cannot measure, aim for the middle, about 22 inches, and follow your pattern's sizing for that head size. Your pattern's size notes tell you how much stretch it builds in.
What size are mittens for a 5-year-old?
The Craft Yarn Council's 4 to 6 year size lists a hand circumference of 6 inches and a hand length of 4¾ inches. If the child is near the top of that band, the 6 to 8 year size (6½ inches around, 5¼ inches long) gives room to grow.
Is there a standard size for a crochet blanket?
Not from the Craft Yarn Council, whose sizing standards cover body measurements and garment fit and length, not blankets. Patterns and stores use their own names and dimensions. The safest method is to measure the mattress or the person and add the drop you want, as in the worksheet above.
How long should a crochet scarf be?
There is no published standard; length depends on how the person wears it. The most accurate shortcut is to measure a scarf they already own. Otherwise, measure around your own neck and down to where you would want the ends, using the style table above.
Do men's and women's mittens differ in size?
Yes, in the Craft Yarn Council charts a man's medium hand is 8½ inches around and a woman's medium is 7½ inches. A woman's large and a man's small share the same measurements (8 inches around, 7½ inches long).

How this article was made
Written by the PLoMUS Editorial Team with AI drafting assistance; facts checked against the sources above on October 27, 2026. The hat and mitten values are the Craft Yarn Council's; the combined layout, scarf table, blanket diagram, formula and worked example are our own. We did not make, measure or test any of these gifts, and the example mattress size is an input for the math, not a standard. We will recheck the Craft Yarn Council charts once a year.
