How to measure a t-shirt and every other garment.

Pick a garment and a point of measure: the line lights up on the flat and the steps tell you where the tape starts and stops. Then print a blank measurement chart for your sample.

Points of measure

Pick a garment, then a point: see exactly where to measure.

Each red line is one point of measure (POM). Tap a line or a name to light it up and read where the tape starts and stops. Lay the garment flat on a table, smooth it without stretching, and measure twice.

How to measure: a t-shirt

Front view. Half measurements are taken flat, edge to edge.
  1. Lay the tee flat, front up, smoothed but not stretched. Measure straight across from side seam to side seam, 2.5 cm (1 in) below the armhole.

  2. Start at the high point shoulder (HPS), where the shoulder seam meets the neck rib. Measure straight down, parallel to the centre front, to the hem edge.

  3. Measure straight across the back from one shoulder point (where the shoulder seam meets the sleeve seam) to the other.

  4. From the shoulder point, measure along the top fold of the sleeve to the sleeve hem edge.

  5. Measure straight across the sleeve hem, edge to edge, with the sleeve lying flat.

  6. Measure in a straight line from the shoulder point to the underarm point where the sleeve seam meets the side seam.

  7. Measure straight across the bottom edge from side to side, relaxed.

  8. Measure straight across from HPS to HPS, seam to seam at the inside edge of the neck rib.

  9. Lay a ruler across from HPS to HPS. Measure straight down at centre front from the ruler to the neck seam.

Want us to do it properly?

In a tech pack every point of measure gets a code, a written how-to, a value for every size and a tolerance, drawn on your own flat. Send us your sample or reference and we spec it.

Step by step

How to measure a t-shirt in eight steps.

The same way a factory QC team checks a finished tee. Write every number down with its unit, then repeat the whole round once to catch slips.

  1. Lay it flat

    Front up on a hard table. Smooth it from the centre out with flat hands; do not pull. Line up the side seams.

  2. 1/2 chest

    Straight across from side seam to side seam, 2.5 cm (1 in) below the armhole. Double it for the full chest.

  3. Body length from HPS

    From the high point shoulder, where the shoulder seam meets the neck rib, straight down to the hem edge.

  4. Shoulder width

    Turn it over. Straight across the back from shoulder point to shoulder point, where the sleeve seams start.

  5. Sleeve length

    From the shoulder point along the top fold of the sleeve to the sleeve hem.

  6. Sleeve opening and armhole

    Straight across the sleeve hem, edge to edge; then a straight line from the shoulder point to the underarm point.

  7. 1/2 hem

    Straight across the bottom edge, side to side, relaxed.

  8. Neck width and neck drop

    HPS to HPS at the inside edge of the rib; then from a ruler laid between the two HPS straight down to the front neck seam.

What you need

  • A flexible tape measure in cm or inches (not both on one chart).
  • A hard, flat table longer than the garment.
  • A ruler for the neck drop.
  • The printable measurement chart above.

Common mistakes

  • Measuring a stretched knit: rib and jersey read long when pulled.
  • Mixing full and half measurements without saying which.
  • Body length from the neck seam on one garment and from HPS on another.
  • No tolerance: a factory then has nothing to check against.

Next: grade your numbers in the size chart generator.

The team behind every pack

Real people draw every tech pack.

Our studio team in the USA drafts every flat, measurement and note, and answers your revision rounds by email. No template generator, no guesswork.

    A second person checks every measurement

    Before delivery, someone who did not draw the pack checks every point of measure against the flats. Then 2–3 revision rounds by email.

Lay it flat, smooth it without stretching and measure: 1/2 chest straight across 2.5 cm (1 in) below the armhole, body length from the high point shoulder to the hem, sleeve length from the shoulder point to the sleeve hem, plus shoulder width, sleeve opening, hem and neck.

A point of measure is one defined measurement on a garment, with a code, a name, a written how-to-measure and a tolerance, for example B, body length from HPS. The POM table in a tech pack lists every one, graded for every size.

HPS is the high point shoulder: where the shoulder seam meets the neckline. Body lengths are measured from it, so the length does not change with the neckline shape.

Factories measure garments lying flat, edge to edge, which gives half the circumference. A 1/2 chest of 54 cm is a 108 cm chest all round. Always say which one you mean in the POM name.

For a tech pack, measure the garment: the finished product the factory makes. Body measurements go on your store’s size guide, and the difference between the two is the ease.

Measure to the nearest 0.5 cm or 1/8 in, twice, on a flat, unstretched garment. Then set a tolerance per point, commonly ±0.5 to ±1 cm on body measurements, and tighter on small details like a neck rib.
