Quilt Sizes Chart: Standard Dimensions for Every Bed & Style
Quick answer: A queen quilt is 90" x 108" (with a 15" drop on three sides). A throw quilt is 50" x 65". The standard sizes below include mattress dimensions, recommended drop, and finished quilt size for every bed from crib to California king. Need custom dimensions? Use the quilt size calculator.
I made a queen quilt using twin dimensions once. Measured the top of the mattress, cut the fabric, quilted the whole thing. Looked beautiful. Covered exactly the mattress surface with zero drop on any side. Every time someone rolled over, they pulled the quilt off the other person. Took me another 40 hours to add side borders.
Quilt sizing is different from blanket sizing because quilts typically include drop — the fabric that hangs over the mattress edges and foot. Skip the drop and you have an expensive mattress pad. Get the drop right and you have a quilt that stays put and looks finished.
Complete Quilt Sizes Chart
This is the reference chart. "Drop" is the overhang on each side and the foot. Pillow tuck adds 8–12 inches at the head for folding over pillows.
| Quilt Type | Finished Size | Mattress | Drop | Pillow Tuck |
|---|---|---|---|---|
| Wall Hanging | 36" x 36" | — | — | — |
| Mini / Doll | 18" x 24" | — | — | — |
| Baby / Crib | 36" x 52" | 28" x 52" | 4" sides | None |
| Toddler | 42" x 58" | 28" x 52" | 7" sides | None |
| Lap / Throw | 50" x 65" | — | — | — |
| Twin | 70" x 90" | 39" x 75" | 15" sides, 15" foot | Optional |
| Twin XL | 70" x 95" | 39" x 80" | 15" sides, 15" foot | Optional |
| Full / Double | 85" x 95" | 54" x 75" | 15" sides, 15" foot | 5" tuck |
| Queen | 90" x 108" | 60" x 80" | 15" sides, 15" foot | 13" tuck |
| King | 108" x 108" | 76" x 80" | 16" sides, 16" foot | 12" tuck |
| California King | 104" x 108" | 72" x 84" | 16" sides, 12" foot | 12" tuck |
The difference between a king (76" wide mattress) and California king (72" wide mattress) is small in width but noticeable in length — Cal kings are 4 inches longer. A standard king quilt often works on a Cal king, but it'll be slightly wider than needed with slightly less foot coverage.
Understanding Quilt Drop
Drop is what separates a quilt from a mattress cover. Here's how to think about it.
| Drop Amount | Effect | Best For |
|---|---|---|
| 0–5" | Covers mattress top only | Quilt used with a bed skirt |
| 8–12" | Covers top + part of sides | Coverlet style, modern look |
| 14–16" | Covers to just above the bed frame | Traditional quilt look |
| 18–21" | Covers to near the floor | Bedspread style, no bed skirt needed |
Modern pillow-top mattresses are 14–16 inches deep. If your mattress is deeper than average, add 2–4 inches to each side of the standard quilt size. The chart above assumes a standard 12-inch mattress depth.
To calculate your custom drop: measure from the top of the mattress to where you want the quilt to end. That measurement is your drop. Then: quilt width = mattress width + (2 x drop). Quilt length = mattress length + drop (foot) + pillow tuck.
The quilt size calculator does this math for any mattress dimension and desired drop.
Fabric Yardage by Quilt Size
This is where quilt sizing gets expensive. The yardage depends on whether you're doing a simple quilt (few fabrics, large pieces) or a complex patchwork (many fabrics, small pieces).
For backing fabric (single fabric, full width), you need:
| Quilt Size | Backing Yardage (44" fabric) | Backing Yardage (108" fabric) |
|---|---|---|
| Baby (36" x 52") | 1.75 yds | 1.5 yds |
| Throw (50" x 65") | 3.5 yds | 2 yds |
| Twin (70" x 90") | 5.5 yds | 2.75 yds |
| Full (85" x 95") | 7.75 yds | 3 yds |
| Queen (90" x 108") | 8.25 yds | 3.25 yds |
| King (108" x 108") | 9.75 yds | 3.25 yds |
Wide-back fabric (108 inches) eliminates piecing for everything up to a king quilt. It costs more per yard but saves time and fabric waste. For anything queen-size or larger, wide-back is worth the premium.
For quilt top patchwork yardage, the calculation depends entirely on block size and pattern. A simple rail fence quilt in four fabrics uses roughly 6–8 yards of total fabric for a queen. A complex sampler with 20 different fabrics might use 10–15 yards total. The pattern should specify yardage — if it doesn't, multiply the number of blocks by the fabric per block and add 15% for cutting waste.
Batting Sizes (Standard Packaged)
Batting is sold in pre-cut sizes that roughly match standard quilt dimensions. "Roughly" being the operative word — batting should extend 2–4 inches beyond the quilt top on all sides for quilting ease.
| Batting Package | Dimensions | Fits Quilt Size |
|---|---|---|
| Crib | 45" x 60" | Baby, Toddler |
| Twin | 72" x 90" | Twin |
| Full | 81" x 96" | Full |
| Queen | 90" x 108" | Queen |
| King | 120" x 120" | King, Cal King |
For throw quilts and wall hangings, you'll often need to buy the twin-size batting and cut it down. Or buy batting by the yard from a roll — most quilt shops sell it in 90" or 96" widths.
Block Count by Quilt Size
If you're building a block-based quilt, here's how many blocks you need for common block sizes. These assume no sashing (strips between blocks). Add sashing and the block count drops.
| Quilt Size | 6" Blocks | 8" Blocks | 10" Blocks | 12" Blocks |
|---|---|---|---|---|
| Baby (36" x 48") | 48 (6x8) | 24 (4x6) | 20 (4x5) | 12 (3x4) |
| Throw (48" x 64") | 80 (8x10) | 48 (6x8) | 30 (5x6) | 20 (4x5) |
| Twin (68" x 88") | 154 (11x14) | 88 (8x11) | 63 (7x9) | 42 (6x7) |
| Queen (88" x 104") | 260 (14x18) | 143 (11x13) | 90 (9x10) | 72 (8x9) |
| King (104" x 104") | 289 (17x17) | 169 (13x13) | 100 (10x10) | 81 (9x9) |
Borders are the quilter's best friend for size adjustment. A 3-inch border on all sides adds 6 inches to both width and length. That turns a 84" x 100" quilt top into a 90" x 106" quilt — close enough to queen. They also frame the design and give your eye a resting place.
Quilt Binding Requirements
Every quilt needs binding to finish the edges. For a quick estimate:
| Quilt Size | Perimeter | Binding Strip Length |
|---|---|---|
| Baby | 176" | 210" (6 yds) |
| Throw | 230" | 275" (7.75 yds) |
| Twin | 320" | 380" (10.5 yds) |
| Queen | 396" | 470" (13 yds) |
| King | 432" | 510" (14.25 yds) |
FAQ
What size quilt do I need for a queen bed?
A standard queen mattress is 60" x 80". With a 15-inch drop on three sides and a pillow tuck at the head, the finished quilt should be approximately 90" x 108". If you use a bed skirt or prefer a shorter drop, you can go as small as 86" x 96". Measure your specific mattress and decide where you want the quilt to end before cutting fabric.
What's the difference between a coverlet and a quilt size?
A coverlet has a shorter drop (8–12 inches) and sits on top of the bed without reaching the frame. A full quilt has a longer drop (14–16 inches) that covers to or past the bed frame. Same mattress, different finished sizes. A queen coverlet might be 82" x 96", while a queen quilt is 90" x 108". Coverlets look more modern and work well layered over sheets with visible bed frame.
Do I need to add seam allowances to the quilt size?
The sizes in the chart above are finished dimensions — the quilt after quilting, trimming, and binding. When cutting your blocks and borders, add quarter-inch seam allowances to each piece. Most patterns already include seam allowances in their cutting instructions. The quilt shrinks slightly (1–3%) during quilting due to fabric take-up, so cut your backing and batting 4–6 inches larger than the finished top.
How do I size a quilt for a thick pillow-top mattress?
Measure the mattress depth from the top surface to the bottom edge. Modern pillow-top mattresses are 14–18 inches deep. Standard quilt sizes assume a 12-inch mattress. If yours is 16 inches deep, add 4 inches to each side of the quilt width (8 inches total) and 4 inches to the length. So a queen becomes 98" x 112" instead of 90" x 108".
Can I use the same pattern for different quilt sizes?
Yes — most block patterns scale by adding or removing blocks and adjusting border width. A 12-inch block pattern for a throw (20 blocks in a 4x5 layout) becomes a queen by going to 72 blocks in an 8x9 layout. The block construction stays the same; you just make more of them. Border width adjustments handle any remaining size differences.
