Batting loft types
| Type | Loft | Best for | Notes |
|---|---|---|---|
| Cotton | Low | Heirloom, machine quilting, warm climates | Shrinks slightly for antique look; breathable |
| Polyester | Low–High | Beginners, wall hangings, puffy quilts | Lightweight, washable, won't shrink; can beard |
| Cotton/Poly Blend | Low–Med | All-purpose quilts | Best of both; popular 80/20 blend |
| Wool | Medium | Hand quilting, warm bed quilts | Naturally warm, easy to needle; dry clean or gentle wash |
| Bamboo | Low | Eco-friendly, summer quilts | Soft, breathable, moisture-wicking |
| Fusible | Low | Wearables, small projects | Bonds with heat — no basting required |
How much overhang do I need?
Standard quilting practice is to cut batting 4–8 inches larger on each side than the quilt top. This gives you room to re-square the quilt, handle any shifting during quilting, and ensure the backing doesn't pull tight. Longarm quilters often ask for 4" on each side minimum.
Batting by the yard vs. packaged
Packaged batting comes in pre-cut sizes (crib, throw, twin, etc.). Batting by the yard comes on a bolt, typically 90"–120" wide, and is great for oversized or odd-shaped quilts. When using packaged batting, choose the next size up from your minimum needed dimensions.
