Size & Cost Guide
How Many T-Shirts for a T-Shirt Quilt?
Shirt counts by quilt size, how to keep stretchy tee fabric from distorting, and what it typically costs to have one made.
Shirts Needed by Quilt Size (14″ blocks)
| Quilt Size | Grid | Shirts Needed |
|---|---|---|
| Baby / Crib | 2×2 | 4 |
| Throw / Lap | 3×4 | 12 |
| Twin | 3×5 | 15 |
| Full / Double | 4×5 | 20 |
| Queen | 5×6 | 30 |
| King | 6×6 | 36 |
Assumes one 14″ block per shirt with 2.5″ sashing and a 3″ border. Fewer, larger blocks (16″+) need fewer shirts; smaller blocks (12″) need more. Use the block calculator for other block sizes.
Stabilizing T-Shirt Fabric Before Cutting
Jersey knit stretches in every direction, which makes it distort and ripple if pieced like quilting cotton. Before cutting a design area from a shirt, iron a lightweight fusible interfacing (knit-specific interfacing gives the best drape) to the wrong side of the fabric, covering the whole area you plan to cut. This locks the knit to a stable, non-stretch backing so it cuts and sews like woven cotton.
Cut each interfaced block a consistent size — 14″ square is a common choice, oversized enough to include most graphics (including larger back-of-shirt designs) without excessive plain background. Center the design in the block before the final trim.
What a T-Shirt Quilt Typically Costs
| Quilt Size | Estimated Cost (made-for-you) |
|---|---|
| Throw (12 shirts) | $150–$300 |
| Twin (15 shirts) | $180–$360 |
| Full (20 shirts) | $240–$480 |
| Queen (30 shirts) | $360–$720 |
| King (36 shirts) | $430–$860 |

Frequently Asked Questions
How many t-shirts do I need for a t-shirt quilt?+
Using a common 14" finished block size with 2.5" sashing: a throw needs about 12 shirts, a twin about 15, a full/double about 20, a queen about 30, and a king about 36. Each shirt typically yields one block (front or back design), though a shirt with graphics on both sides can yield two smaller blocks.
How do I stabilize t-shirt fabric before cutting?+
Iron a lightweight fusible interfacing (knit interfacing works well for jersey material) to the wrong side of the design area before cutting. T-shirt knit fabric stretches and distorts easily; the interfacing keeps blocks square and prevents the graphic from warping during piecing and quilting.
How much does it cost to have a t-shirt quilt made?+
Prices vary widely by maker and region, but a common range is roughly $12-24 per shirt block when a service builds the whole quilt (blocks, assembly, quilting, and binding) — about $150-300 for a 12-shirt throw and $360-720 for a 30-shirt queen. Get a specific quote; some makers price per shirt, others price by finished quilt size.
What size should each t-shirt block be?+
12"-16" finished is the most common range — big enough to show a full design (including larger back prints) without excessive empty space, small enough that most shirt graphics fit without stretching to fill it. 14" is a good default for mixed adult-size shirts.
Can I use shirts of different sizes in one quilt?+
Yes — the interfacing-and-block-frame approach evens everything out. A youth-size shirt's smaller graphic gets extra background fabric (or the interfacing block is fussy-cut to center the design) so every finished block comes out the same size regardless of the original shirt's size.
