The two-minute guide

Find your fit.
First time.

The most reliable method is to measure a shirt that already fits, not your body and not the size printed on its label. Enter the flat width in inches and we will do the doubling and size comparison for you.

Important

The charts show the finished garment measurement, not the body measurement. Measure a shirt flat from armpit to armpit. The finder doubles that width automatically before recommending a size.

Put in your measurements.

Shirt sizing is required. Shorts are optional. Both measurements come from garments that already fit, laid flat without stretching.

  1. 01
    Choose a shirt that fits

    Lay it flat and smooth it naturally. Do not measure around your body.

  2. 02
    Measure armpit to armpit

    Run the tape straight across the chest in inches. Enter that single flat width.

  3. 03
    We double it for you

    The finder compares the full garment chest with the SQD chart and suggests the closest size.

Measure the garment, not the person.

Use a shirt that fits the way you like. We will double its flat chest width and compare it with the finished-garment chart. If adding shorts, keep the elastic completely relaxed.

Do not stretch or pull the elastic. Measure the relaxed waistband straight across. Leave blank if shorts are not needed.
Fit tip

For a baggier, freer fit, we always recommend choosing one size up.

Measure properly

A tape. Two minutes.

The most common mistake is comparing a flat half-width with a full finished-garment measurement. The finder above performs that doubling automatically.

Tops and jackets

Required shirt measurement: lay a garment that fits flat and measure straight from armpit seam to armpit seam. The finder doubles it.

Shorts

Waist: lay the shorts flat and measure the relaxed waistband straight across, then double it. Never stretch the elastic. Inseam: crotch seam to inner-leg hem.

Before you order

The questions we get most.

My child is big or small for their age. What should I choose?

Ignore the age label and measure a garment that currently fits them. Match the actual chest and length. If the two measurements point to different sizes, choose the larger size and ask SQD if you are unsure.

I am between two sizes. Which one should I choose?

Choose the larger size for normal sports movement, layering or growing room. Only choose the smaller option when you deliberately want a close fit and the length still works.

Does the chest column mean flat width?

No. It is the full measurement around the finished garment. A shirt measuring 20 inches flat across the chest is 40 inches around, which matches an SQD football jersey size S.

Will every product fit exactly the same?

No. That is why each product has its own chart. Dry robes are deliberately oversized, padded jackets allow for layers, and elasticated shorts behave differently from tops.

Still not certain?

Send the product and measurements to SQD before placing the order. We would rather check it now than swap a personalised kit later.
