The Australian Clothing Size Guide: How to Find Your Size in Any Garment

Why Sizing Clothing in Australia Is More Complicated Than It Should Be

You find a polo you want for your cafe team. The spec sheet says "M (half chest 50cm)." Half your staff say they're a medium. But a medium at one Australian retailer is not the same as a medium at a US supplier, and the sizing guide from that UK wholesaler is using EU numeric labels. Three weeks later, 12 shirts arrive embroidered and a third of them don't fit.

This guide exists so that doesn't happen to you.

Whether you're ordering a single tee for yourself or 200 polo shirts for a hospitality group, you'll find what you need here: actual measurement charts, AU to US/UK/EU conversion tables, garment-specific fit notes, and a practical framework for collecting sizes from a team without reorders.

The same approach applies whether you're sizing blank t-shirts, polo shirts, hoodies, or pants and shorts: only the measurement you anchor against changes.

How to Measure Yourself

The starting point for any size decision is your body measurement, not what you "normally wear." What you normally wear reflects one brand's interpretation of a medium, and that may not match the garment you're about to order.

You'll need a soft tape measure. Have someone help you if you can; self-measuring often produces readings that are 2-3 centimetres off.

Chest (most important for tops)

Measure around the fullest part of your chest, keeping the tape parallel to the floor. Keep the tape snug but not tight. Breathe normally. This is your body chest circumference in centimetres.

Waist

For pants and shorts, measure your natural waist: roughly 2 centimetres above your navel, not where your pants normally sit. Keep the tape flat and level.

Hips

Stand with your feet together and measure around the fullest part of your hips. Used for women's pants sizing and some fitted styles.

Sleeve (for jackets and long-sleeve styles)

Measure from the centre back of your neck, across the top of your shoulder, and down to your wrist with your arm slightly bent. This gives you the full sleeve length in centimetres.

Inseam (for pants)

Measure from your crotch seam to your ankle bone on the inside of your leg. If you have a pair of pants that fit well, measuring the inseam of that garment is more reliable than measuring your body.

Reading a BCA Size Chart

BCA size charts use a specific format that is worth understanding before you look at any spec sheet.

What "half chest" means

Almost every BCA garment is measured using "half chest" rather than full chest circumference. Half chest is the flat measurement of the garment laid on a table from one side seam to the other across the chest. It is exactly half the total garment chest circumference.

To find your target half chest: take your body chest measurement, add your preferred ease allowance, and divide by 2.

• Regular fit: add 10-14 centimetres of ease, then divide by 2
• Relaxed or boxy fit: add 16-20 centimetres, then divide by 2
• Oversized: add 22-28 centimetres, then divide by 2

Example: your chest measures 96 centimetres. You want a regular fit. (96 + 12) divided by 2 = 54cm. You need a garment with a half chest of approximately 54cm, which is a size L in most BCA polo and tee ranges.

Body length and sleeve length

Body length is measured from the high point of the shoulder down to the hem. Sleeve length is measured from the shoulder seam to the cuff. Both are listed in centimetres.

Fit notes: slim, regular, relaxed

Many BCA spec sheets include a fit note. Slim means the garment is cut close to the body with less ease built in. Regular is the standard for most work and casual garments. Relaxed means there is generous ease; the garment will sit away from the body.

Tolerance

Manufacturing tolerance of plus or minus 1-2 centimetres is normal across all garments. If you are right on the boundary between two sizes, always check the fit note and err toward the larger size.

Same alpha size, different measurements across garments

A size M polo and a size M hoodie from the same supplier will have different half chest measurements. The polo is designed to sit closer to the body; the hoodie is cut to wear over a layer. Always pull the spec sheet for the specific garment you are ordering.

AU to US, UK, and EU Size Conversions

Women's Clothing: AU/UK to US and EU

Australian and UK women's clothing sizes use the same numeric scale. US sizes are 4 lower than AU. EU uses a different numeric system.

Note: this is a general industry conversion guide. Individual brands vary. Always confirm against the specific garment's measurement chart using your body measurements.

Men's Alpha Sizing: AU/UK/US vs EU

Jeans and Pants: Waist Sizing

"What size is 28 jeans in Australia?" A waist size 28 corresponds to roughly AU 8-10 in women's pants sizing, depending on the cut and brand. The most reliable reference is your body waist measurement: if your waist measures 70-72 centimetres, you are at the 28/AU 10 boundary.

European Clothing Sizes to Australian: Quick Reference

For men's EU numeric to AU alpha: EU 46 is approximately AU/US S, EU 48 is M, EU 50 is L, EU 52 is XL. Always validate against the chest measurement column on the spec sheet.

Garment-by-Garment Fit Notes

Tees

Standard cut tees are the most forgiving category for sizing.

• Standard fit: match your half chest target (chest + 10-12cm ease, divided by 2)
• Oversized or drop-shoulder styles: choose the size that covers your chest normally and you will get the look without drowning in fabric. Size up if you want a longer body drop
• Women's fitted tees: cut narrower in the torso and shorter in the body than unisex styles; AU women's alpha sizing applies
• Kids' sizes: typically run as 2, 4, 6, 8, 10, 12, 14; these are Australian age-based sizes that correspond to chest measurements. Always check the spec sheet

Polos

Polos typically run slimmer in the torso than equivalent tees because the fabric (usually a fine pique knit) has less stretch than a jersey tee.

• Regular polo fit: "slim" polos often require sizing up one step from your half chest target
• Premium styles vs standard styles: premium fine-knit polos often have a smaller ease allowance built in; standard polyester-cotton polos tend to run more generously
• Women's polos: typically come in fitted AU women's alpha sizing

Hoodies

Hoodies are the category where people most consistently order the wrong size, because they measure themselves, match a size, and forget they will be wearing something underneath.

• Pullover vs zip-through: for most BCA ranges, the half chest measurement is the same for pullover and zip styles at the same alpha size
• Layering allowance: for a garment worn over a shirt or light base layer, add an extra 5-8cm to your ease calculation before dividing by 2
• Unisex sizing and women's fit: unisex hoodies are cut against male body proportions. Women who want a fitted look typically size down one from their standard alpha
• Fabric weight and perceived fit: a 340gsm+ heavy fleece will feel closer to the body than a 280gsm fleece at the same half chest measurement. If you are between sizes in a heavyweight hoodie, size up

Jackets

• Softshell jackets: true-to-size alpha sizing works for most people. If you are wearing a bulkier inner layer, size up one
• Puffer and padded jackets: the padding adds volume inside the garment. Sizing up is the conservative call for anyone between sizes
• Hi-vis workwear: must comply with AS/NZS 4602.1:2011. Size selection must use the garment measurement table, not just alpha. For fit-compliance questions, BCA's team can advise
• Workwear (heavy cotton canvas, drill): typically runs true to men's alpha for chest

Browse BCA's jackets range for full spec sheets per style.

Pants and Shorts

• Waist sizing (numerical): the most reliable spec. Numerical waist sizes refer to waist in inches and are consistent across AU/US/UK markets
• Inseam: check the spec sheet against your inside leg measurement. Most BCA work pants come with hem allowance for alteration
• Drawstring waist: confirm your waist measurement falls within the stated range
• Zip fly with waistband: use your body waist in centimetres and match directly to the spec sheet
• Women's pants and shorts: may come in AU numeric sizing or in waist centimetres

Sizing for Teams and Bulk Orders

This is where incorrect sizing becomes an actual cost. A team of 30 people who each self-report "I'm a medium" will almost always produce the wrong distribution for the actual team.

The size distribution benchmark

For a typical mixed Australian workplace team, a useful starting distribution is:

Based on standard apparel industry ordering patterns; your team's actual distribution will vary by industry, gender mix, and role type. Use this as a starting framework, not a guarantee.

A gym staff team will skew L/XL. A school administration team may skew toward women's fit ranges. A trades business will likely need more 2XL and 3XL than average.

How to collect accurate sizes from your team

1. Share a link to this size guide and the specific garment's spec sheet with your team
2. Ask each person to report either: their actual chest measurement in centimetres, or their "normally wear" alpha size plus the brand they are referencing
3. Cross-reference reported brand sizes against BCA's half-chest measurement for the specific garment
4. Where someone is on the boundary between two sizes and cannot try a sample, recommend they go up one

Decorated garments and size corrections

Once a garment is printed or embroidered, returns based on sizing are not possible. For any bulk order over 20 pieces that will receive chest printing or embroidery, request a sample set in your borderline sizes before committing.

The size-up rule for decorated garments

If a garment will carry a large centre-chest print (A4 size or larger), anyone who is borderline between two sizes should go up one. The print positions better proportionally on the larger garment.

Decoration and Sizing

Most sizing guides stop before this section. For anyone ordering decorated garments, the interaction between print size and garment size is worth understanding.

Centre chest prints and garment size

The print area available on a garment scales with garment size. On a size S adult tee, the usable centre chest print zone is approximately 20-22 centimetres wide. On a size L it is 24-26 centimetres. On a size 2XL it is 28-30 centimetres.

If your artwork is fixed at 25 centimetres wide and a portion of your team is in size S, the print will look proportionally oversized on the smaller garments. This is not a quality issue; it is a physics issue.

Always share your artwork dimensions with BCA's decoration team before locking in your order distribution.

Embroidery: where size matters less

Left chest embroidery is less size-sensitive than a chest print. The embroidery patch sits in a fixed position regardless of garment size. Exceptions: sleeve embroidery on cropped styles may sit differently depending on sleeve length.

Print method and garment sizing

• Screen printing: placement is measured from the collar or hem at a fixed distance, not proportionally to garment size
• DTF (direct-to-film) transfers: the carrier film is a fixed size; placement is also fixed
• Embroidery: no bleed, no proportional scaling issue

For any garment receiving decoration, BCA's decoration team can provide a placement overlay for your artwork.

FAQ

Getting Your Order Right the First Time

Clothing size conversions are not complicated once you have the reference tables. The part that trips people up is trusting a brand alpha label over an actual measurement, and that mistake costs more per unit when the garments are already decorated.
