How to measure yourself

What you need to measure yourself at home

• A soft tape measure — the flexible cloth or vinyl kind used for sewing. No tape? Use a piece of string, mark it, and lay it against a ruler afterwards.
• A mirror or a helper. A second pair of hands keeps the tape level across your back; a mirror works if you’re on your own.
• Thin, fitted clothing or underwear. Measure over skin or a t-shirt, never over a sweater or jeans.
• Somewhere to write the numbers down — a note on your phone is fine. You’ll reuse them every time you shop.

Stand relaxed and upright, breathe normally, and keep the tape level all the way around and snug against your body without digging in. Write each number in both centimetres and inches so you’re ready for any size chart.

How to measure your bust or chest

Where to place the tape: wrap it around the fullest part of your bust or chest, level under the arms and straight across the shoulder blades at the back. Read the number on a relaxed breath.

Common mistake: letting the tape ride up at the back, or pulling it tight enough to flatten the chest. It should sit horizontal and just touch the skin.

Tip: bust or chest drives tops, shirts, dresses and jackets — get this one right first.

How to measure your waist

Where to place the tape: find your natural waist — the narrowest part of your torso, usually about level with your belly button and above your hip bones — and wrap the tape level to the floor, snug but not tight.

Common mistake: measuring where the waistband of your jeans sits (usually lower) instead of your natural waist, or sucking your stomach in. Stand normally so the number reflects real life.

Tip: to find your natural waist, bend gently to one side; the crease that forms is roughly where it is.

How to measure your hips

Where to place the tape: stand with your feet together and wrap the tape around the fullest part of your hips and seat, level all the way around. Feet together matters — a wide stance changes the reading.

Common mistake: measuring too high, at the hip bones rather than the fullest point, or letting the tape dip at the back. Check in the mirror that it’s parallel to the floor.

Tip: hips drive skirts, trousers and dresses; cross-check them against your waist when a chart lists both.

How to measure your inseam

Where to place the tape: the inseam runs along the inside of your leg from the crotch seam to where you want the hem, around the ankle. The easiest way is to lay a pair of well-fitting trousers flat and measure from the crotch seam straight down the inside leg to the hem.

Common mistake: measuring the outside of the leg, or forgetting the shoes you’ll actually wear. Decide where you want the hem to fall and measure to that point.

Tip: inseam controls trouser and jean length — it’s why two people with the same waist can need different lengths.

How to measure sleeve length and shoulders

Where to place the tape: for shoulder width, measure across your back from the bony edge of one shoulder to the other. For sleeve length, start at the shoulder edge and run the tape over a slightly bent elbow down to the wrist bone.

Common mistake: measuring with a straight arm. Keep the elbow slightly bent so the sleeve isn’t too short once you move. This is the one where a helper really helps.

Tip: shoulders and sleeves matter most for shirts, blazers and coats, where a shoulder line is hard to alter.

Common measuring mistakes to avoid

• Measuring over bulky clothes. Sweaters and jeans add bulk and push you towards a size that’s too big.
• Pulling the tape too tight. Snug, not compressing — you want your real measurement, not a squeezed one.
• Letting the tape tilt. If it isn’t level all the way around, every number drifts. Use a mirror or a helper.
• Holding your breath or your stomach. Measure the body you’ll actually wear the clothes on.
• Mixing units. Don’t compare inches with a centimetre chart. One inch is 2.54 cm.

How to turn your measurements into a size

Letter sizes like S, M and L aren’t standardised, so the same letter can mean different measurements in different brands. Your numbers are what decide the size — the letter is just the label the brand puts on them.

1. Open the size chart for the exact piece, not a generic one; charts can differ between a brand’s lines.
2. Pick the measurement that matters for that garment: bust or chest for tops and dresses, waist and hips for bottoms, inseam for length.
3. Between two sizes? Size up for stiff or structured fabrics, relaxed fits and layering pieces; size down only for very stretchy knits if you like a snug fit.
4. Compare brands quickly with our clothing size converter: enter your bust, chest or waist in cm and it shows the size to start with in each brand, built on the brands’ own published charts.

Why measurements and a studio shot of you work together

Measurements answer will it close? They can’t answer how will it look on me? — where a hem lands on your frame, whether a colour suits you, how a cropped jacket works with high-waisted trousers.

That’s the part wearfits.me covers. Add a selfie with your height and weight (a full-body photo is optional and raises accuracy), then paste a product link from almost any shop. You get a studio shot of you wearing the piece, like the model on the product page — no prompts to write. You can also mix pieces from several shops into one look.

The shot is a visual preview, not a size guarantee. Use your measurements and the brand’s chart to choose the size, and the shot to decide whether you like it on you. See how to try on clothes online for the steps.
