How to Measure Yourself at Home, in the Right Order

Most of us have never measured ourselves as adults. We know the size we settled on years ago and have been treating brand differences as a personal problem ever since. Twenty minutes with a soft tape fixes more than any conversion chart, because the numbers are about you, not an average.

What you need

• A soft tape that doesn’t stretch. If yours is old and fabric-backed, check it against a rigid ruler. A stretched tape quietly tells you you’re smaller than you are.
• A mirror, or a helper. Someone else measuring your back and shoulders is more reliable than reaching around.
• Light clothing and the bra you actually wear. Underwear shifts bust and underbust more than anything else.
• A pen or phone note. Unwritten measurements get retaken next month.

Take the tape seriously

Two habits separate usable numbers from misleading ones.

Keep it level. Front and back at the same height. On a larger hip, a tape that dips at the back can read several centimeters (an inch or more) wider than you are. Run your fingers around it to check it’s parallel to the floor.

Snug, not tight. It should touch skin all the way around without compressing. Pull in soft tissue and you’ve measured a shape the garment won’t meet. The opposite mistake, holding the tape away from you, is common when measuring your own bust and overstates it.

Measure each spot twice and use the bigger number if they differ. Your shape shifts through the day and with posture, so this is approximate by nature.

The order

Top down, then recheck the waist from behind at the end.

1. Bust. Fullest part, tape level, arms down. Most charts are built on this.
2. Underbust. Right under the bust, tape firm on your ribs. For bras and anything with a band or empire line.
3. Waist. Bend sideways; the crease is your natural waist. Measure there, at the narrowest point, not where your waistband usually sits. Note both if they differ.
4. High hip. About a hand’s width below the waist, over the top of the hip bone. Decides whether fitted skirts and high-waisted trousers pull.
5. Hip. Fullest part of hip and seat, feet together, tape level. Often your largest measurement.
6. Upper arm. Fullest part, arm relaxed. Decides sleeve fit, and plus patterns get it wrong most often.
7. Thigh. Fullest part, weight even on both feet.
8. Rise. From natural waist at the front, down through the crotch and up to the natural waist at the back. A loop, not a line, and easier with help.
9. Inseam. Crotch seam to hem on a comfortable trouser you own. More accurate than measuring your leg.
10. Shoulder. Across the back, bony point to bony point. Get help.

Date it all. Re-measure every six months or after a big weight change, and treat numbers over a year old as rough.

Brands don’t agree on where “waist” is

Worth knowing before you compare charts. Torrid’s guide says to measure the waist “at your natural waistline and across your belly button.” Eloquii says “the narrowest part of your torso.” Universal Standard says the narrowest point, “typically an inch or two above your belly button,” and puts the hip 7–9 in (18–23 cm) below that. On a body where the narrowest point and the navel are far apart, those can be different numbers, so read each brand’s instructions before you match yours to its chart. (All per the brands’ size guides, checked Oct 2026.)

Which numbers actually decide fit

A chart asks for three; you have ten. The extras are tiebreakers.

• Waist-to-hip difference. Decides whether something that fits one end gapes or pulls at the other. Much wider at the hip than the chart assumes? Buy for the hip and have the waist taken in.
• High hip. Decides whether fitted skirts lie flat or roll down.
• Upper arm. Decides whether a sleeve is wearable, and a tailor can’t fix it cheaply.
• Rise and inseam together. Decide whether trousers sit where you want. Neither replaces the other.

If a chart gives two plausible sizes and the garment has no stretch, buy for your largest relevant measurement and alter down. Taking in is easier, cheaper and more reversible than letting out, which is often impossible because ready-to-wear rarely leaves seam allowance.

Measure a garment instead

For online shopping, a garment you already own beats body measurements. Lay a favorite piece flat, smooth it, and measure across bust, waist and hip, side seam to side seam. Double each for the circumference. Compare with the chart’s body measurement and you’ve got the garment’s ease, meaning how much room it leaves.

That’s how you size yourself in a new brand without ordering twice. If a chart says a size 22 has a certain hip, and your best-fitting piece measures half that flat, you know it lines up before you pay.

None of these numbers judge anything. They let you compare a figure you know is accurate against a chart that’s usually a guess.
