Crochet Blanket Sizes: Standard Dimensions, Stitch Counts & Yarn Needed
Quick answer: A throw blanket is 50" x 60". In worsted weight with an H/8 hook (standard gauge ~14 sc per 4"), you need a starting chain of about 175 and 210 rows of single crochet, using roughly 3,000–3,300 yards of yarn. Full size chart, stitch counts, and yarn estimates below. Get precise numbers with the crochet blanket calculator.
My first crochet blanket was supposed to be a throw. It ended up the size of a twin bed because I guessed the chain count instead of measuring. That was 4,000 yards of yarn and six weeks of work on a blanket that hangs a foot over each side of the couch. Measure first. Chain second.
The stitch counts in this guide assume standard gauge for each hook size. Your actual count depends on your personal tension, but these numbers get you within a few inches of target — close enough to adjust after a test swatch.
Standard Crochet Blanket Sizes
These are the dimensions used in the vast majority of published crochet blanket patterns. They're based on standard mattress sizes with appropriate overhang for bed blankets, and common use cases for non-bed blankets.
| Blanket Type | Width | Length | Common Use |
|---|---|---|---|
| Lovey | 12" | 12" | Infant security blanket |
| Preemie | 18" | 24" | NICU, hospital donations |
| Baby | 30" | 36" | Crib, tummy time, car seat |
| Stroller | 30" | 40" | Stroller, toddler naps |
| Lap | 36" | 48" | Wheelchair, lap coverage |
| Throw | 50" | 60" | Couch, single person |
| Twin | 66" | 90" | Twin bed with 10" drop |
| Full/Double | 80" | 90" | Full bed with 10" drop |
| Queen | 90" | 100" | Queen bed with 12" drop |
| King | 108" | 100" | King bed with 12" drop |
For a couch throw, 50" x 60" is the standard most people expect. Going to 54" x 70" gives you more wrapping room without becoming a bed blanket. It's my preferred size for gift throws.
Stitch Count by Blanket Size (Single Crochet)
This chart uses single crochet at a standard worsted weight gauge: H/8 hook (5.0 mm), approximately 3.5 stitches per inch, 4 rows per inch.
| Blanket Size | Width | Starting Chain | Rows | Total Stitches |
|---|---|---|---|---|
| Lovey | 12" | 43 | 48 | 2,064 |
| Baby | 30" | 106 | 144 | 15,264 |
| Stroller | 30" | 106 | 160 | 16,960 |
| Lap | 36" | 127 | 192 | 24,384 |
| Throw | 50" | 176 | 240 | 42,240 |
| Twin | 66" | 232 | 360 | 83,520 |
| Full/Double | 80" | 281 | 360 | 101,160 |
| Queen | 90" | 316 | 400 | 126,400 |
| King | 108" | 379 | 400 | 151,600 |
A queen-size blanket in single crochet is 126,400 individual stitches. At a pace of 30 stitches per minute (experienced crocheter), that's roughly 70 hours of crocheting. Spread over evenings and weekends, expect 2–3 months for a bed-size blanket in single crochet.
Stitch Count by Blanket Size (Double Crochet)
Double crochet is faster because each stitch is taller. You need fewer rows for the same length. Gauge: H/8 hook, approximately 3.25 stitches per inch, 2 rows per inch (dc).
| Blanket Size | Width | Starting Chain | Rows (dc) | Total Stitches |
|---|---|---|---|---|
| Lovey | 12" | 40 | 24 | 960 |
| Baby | 30" | 99 | 72 | 7,128 |
| Stroller | 30" | 99 | 80 | 7,920 |
| Lap | 36" | 118 | 96 | 11,328 |
| Throw | 50" | 164 | 120 | 19,680 |
| Twin | 66" | 216 | 180 | 38,880 |
| Full/Double | 80" | 261 | 180 | 46,980 |
| Queen | 90" | 294 | 200 | 58,800 |
| King | 108" | 352 | 200 | 70,400 |
The trade-off: double crochet fabric is looser, more open, and less dense than single crochet. For a warm winter blanket, single crochet or half double is better. For a lighter, drapier throw, double crochet wins.
Yarn Yardage by Blanket Size
This is the number most people actually need. All estimates assume worsted weight (#4) yarn in single crochet. For double crochet, reduce by 10–15%.
| Blanket Size | Single Crochet (yards) | Double Crochet (yards) | Skeins (200 yd/skein) |
|---|---|---|---|
| Lovey | 110 | 85 | 1 |
| Baby | 1,000 | 800 | 5 (sc) / 4 (dc) |
| Stroller | 1,150 | 900 | 6 / 5 |
| Lap | 1,600 | 1,300 | 8 / 7 |
| Throw | 3,200 | 2,600 | 16 / 13 |
| Twin | 6,200 | 5,000 | 31 / 25 |
| Full/Double | 7,500 | 6,100 | 38 / 31 |
| Queen | 9,400 | 7,600 | 47 / 38 |
| King | 11,300 | 9,100 | 57 / 46 |
The yarn yardage calculator handles these adjustments. Plug in your dimensions, stitch type, and yarn weight for an accurate number.
A cost reality check: a queen-size single crochet blanket needs 47 skeins. At $5 per skein (budget acrylic), that's $235. At $8 per skein (mid-range), $376. At $12+ per skein (premium or natural fiber), $564+. Blankets are a labor of love and also a labor of expense.
Granny Square Layout by Blanket Size
Granny square blankets need a different kind of math. Here's how many squares you need at the most common sizes (6-inch and 8-inch squares).
| Blanket Size | Dimensions | 6" Squares | 8" Squares |
|---|---|---|---|
| Baby | 30" x 36" | 30 (5x6) | 12 (4x3) |
| Lap | 36" x 48" | 48 (6x8) | 24 (5x6) |
| Throw | 48" x 60" | 80 (8x10) | 42 (6x7) |
| Twin | 66" x 90" | 165 (11x15) | 88 (8x11) |
| Queen | 90" x 96" | 240 (15x16) | 132 (11x12) |
| King | 108" x 96" | 288 (18x16) | 162 (14x12) |
165 granny squares for a twin bed. Each square takes about 15 minutes at a comfortable pace. That's 41 hours of squares, plus another 5–8 hours of joining and weaving in ends. Plan your yarn and your patience accordingly.
Choosing the Right Size
This flowchart saves you from making a blanket that doesn't fit its purpose.
For a baby gift: Go with 30" x 36". It fits a crib, works in a car seat, and doesn't require a massive yarn investment. Parents have told me this is the size they actually use — bigger baby blankets end up in a closet.
For the couch: 50" x 60" throw. Large enough for one adult to curl up under. If two people share the couch, go 60" x 70" — technically between throw and twin, but it works.
For a bed: Match the mattress and add appropriate drop. A common mistake is making a blanket mattress-sized with no overhang — it slides off in your sleep. The sizes in my chart include 10–12" drop on each side.
For a gift (unknown use): Make a 50" x 60" throw in a neutral color. It's universally useful and doesn't require knowing the recipient's bed size or color preferences.
FAQ
How many chains should I start with for a throw blanket?
For a 50" wide throw in worsted weight (H/8 hook, single crochet): chain 176. That gives you 175 stitches across at approximately 3.5 stitches per inch. Always make a gauge swatch first — if you crochet tighter or looser than average, adjust your chain count. The chain count is your width in inches multiplied by your stitches per inch, plus 1 for the turning chain.
How long does it take to crochet a blanket?
A baby blanket (30" x 36"): 10–15 hours. A throw (50" x 60"): 40–60 hours. A queen (90" x 100"): 80–120 hours. These are rough averages for single crochet at a moderate pace. Double crochet is about 40% faster. Your actual time depends on stitch type, yarn weight, and personal speed. Most people crochet 1–3 hours per day, so a throw takes 2–6 weeks.
What's the best stitch for a crochet blanket?
Single crochet makes the warmest, densest blanket. Half double crochet is slightly faster and almost as warm. Double crochet makes a lighter, drapier blanket. Granny squares are portable (you can carry a few squares) and great for using up scrap yarn. For a first blanket, I recommend half double crochet — it's faster than single, warmer than double, and creates a nice texture.
How do I make my blanket lay flat?
Curling or cupping usually means your gauge is off. If the blanket cups inward (bowls up), you're crocheting too tight — try a larger hook. If it ruffles at the edges, you might be adding accidental stitches on the turns. Count your stitches at the end of every row for the first 10 rows until you're confident in your turn technique. Blocking the finished blanket (wetting it and pinning it flat to dry) also corrects minor warping.
Should I add a border to my blanket?
A border makes edges neater and adds 2–4 inches to each dimension. Budget an extra 15–20% yarn for a simple single crochet border (2–3 rounds). A decorative shell or scallop border needs 20–30% extra. If your blanket dimensions already include the border, chain fewer stitches for the body. I add a single crochet border to every blanket — it hides uneven edges and gives a finished look.
Next Steps
- Plug your exact dimensions into the crochet blanket calculator for precise chain counts and yarn estimates.
- Check how much yarn you need per weight in the blanket yardage guide — the estimates work for both knit and crochet.
- Read the crochet hook size guide to make sure you're using the right hook for your chosen yarn weight.
