How to Choose Batting for Your Quilt

Why Batting Deserves More of Your Attention

Batting is the quiet workhorse of every quilt. It sits between your patchwork top and your backing, invisible in the finished piece, yet it decides how your quilt feels, how warm it sleeps and how your quilting stitches read across the surface. Choose well and your quilt drapes beautifully around a sleeping child. Choose badly and you will be wrestling a stiff, lumpy sandwich that fights every stitch.

The good news is that batting is not complicated once you understand what the numbers and fibre names actually mean. This guide walks through loft, weight, fibre content and quilting distance so you can pick with confidence rather than guesswork.

Loft and Weight: What the Labels Are Telling You

Loft is simply how thick the batting is, usually described as low, medium or high. Weight is measured in ounces per square yard, and in the UK you will often see it converted to grams per square metre. As a rough guide, 4 oz per square yard is about 135 gsm, and 8 oz is around 270 gsm.

• Low loft (roughly 2–4 oz / 70–135 gsm): flat and dense. Ideal for wall hangings, table runners and quilts where you want the piecing to shine rather than puffy texture.
• Medium loft (roughly 4–6 oz / 135–200 gsm): the everyday choice. Good drape, enough definition for quilting patterns, warm without being bulky.
• High loft (6 oz and above / 200 gsm plus): puffy and cosy. Brilliant for tied quilts, wholecloth bed quilts and anything you want to feel generous and snugly.

Warmer does not always mean heavier. Wool and down alternatives trap more air per gram, so a mid-weight wool batting can out-warm a heavier polyester one while staying light on the bed.

Natural, Synthetic or Blend?

Fibre content affects drape, warmth, shrinkage and how forgiving the batting is to work with.

• Cotton: Flat, breathable and naturally drapey. It shrinks slightly when washed — often 3–5% — which gives that lovely crinkled antique texture. It has the shortest quilting distance, so it needs denser stitching to stay stable.
• Polyester: Springy, resilient, cheap and widely available. It resists creasing and holds loft well, but it can beard through fabric over time and is less breathable on warm nights.
• Cotton–polyester blends (often 80/20): The reliable all-rounder for beginners. A touch of scrim or resin keeps it stable, it quilts easily by hand or machine, and it shrinks just enough to look softly vintage.
• Wool: Warm, light and wonderful for bed quilts. It drapes superbly, but it costs more and needs gentler washing.
• Bamboo: Silky and cool to the touch, great for summer quilts and baby blankets, though it can be slippery to layer.
• Recycled fibre: Increasingly common in UK quilt shops and a sensible choice if sustainability matters to you. Check the quilting distance, as some are less stable than virgin blends.

Match the Batting to Your Quilting Plan

This is where most disappointment happens. Every batting has a maximum recommended distance between quilting lines, and ignoring it causes shifting, wadding migration and lumpy quilts after washing.

As a general rule, cotton and cotton-rich battings want lines no more than 8–10 inches apart, wool is usually around 4 inches, and polyesters with a scrim can often stretch to 10 inches or more. Always read the label rather than trusting a rule of thumb.

Your stitching style matters too. Dense free-motion quilting on high-loft batting gives spectacular texture but can be hard work — the presser foot sinks and stitches tighten. For intricate designs, choose low or medium loft. If you plan to tie your quilt with yarn rather than stitch it, high loft is your friend because the ties will not compress flat.

Practical Checks Before You Buy

• Measure your quilt, then add 4–6 inches on every side. Batting shifts during basting, and offcuts are useful for cushions and small projects. UK batting often comes precut in single, double and king sizes, or by the metre off a roll — check which before ordering.
• Pre-wash or not? Do not wash most battings. If you want shrinkage, let it happen after quilting, once the stitches are holding everything in place.
• Test for bearding. Rub a scrap against dark fabric to see if fibres work through. If they do, add a tighter-weave backing or choose a needled batting.
• Consider the recipient. A baby quilt wants breathable, washable cotton or bamboo. A sofa throw for winter evenings suits wool or high-loft poly.
• Buy enough in one go. Batches vary slightly, and piecing batting for a large quilt creates a ridge you will feel forever.

Take a moment to feel the samples in your local quilt shop — drape a metre over your arm — and you will learn more in thirty seconds than any description can teach. Choose with your finished quilt in mind, and the batting will quietly do its job for decades.
