Measurement Guide

Measure garments the same way every time so ThriftFit can compare secondhand listings against the clothes that already fit you.

chestshoulderlength

Before you start

Use one setup and repeat it.

Tools

  • Flexible tailor tape
  • Flat table or clean floor
  • Reference garment that fits
  • Notes app or ThriftFit reference editor

Rules

  1. 1. Measure flat, relaxed fabric.
  2. 2. Keep flat width and circumference clearly labeled.
  3. 3. Compare like garment types against each other.

Wovens, overshirts, polos

Shirts

Shirts are easiest to compare when the garment is buttoned, flattened, and measured from stable seam points.

chestshoulderlength

Chest

Pit-to-pit width across the front of a buttoned shirt.

#shirt-chest

How to measure

  1. 1. Button the shirt and smooth the front without stretching.
  2. 2. Measure straight from armpit seam to armpit seam.
  3. 3. Double the number only when a total chest circumference is requested.

Common mistakes

  • xLetting the tape arc upward
  • xMeasuring below the pit seam
  • xMixing flat width with doubled circumference

Why it matters: Chest is the fastest signal for whether the shirt will close and drape cleanly.

Shoulder

Straight distance between the shoulder seam points across the back yoke.

#shirt-shoulder

How to measure

  1. 1. Flip the shirt face down.
  2. 2. Find the outer shoulder seam points.
  3. 3. Measure straight across, keeping the tape level.

Common mistakes

  • xFollowing the curve of the yoke
  • xStarting at the sleeve edge
  • xMeasuring across wrinkles

Why it matters: Shoulder width controls sleeve pitch and how structured the shirt feels.

Sleeve

Sleeve length from shoulder seam to cuff edge.

#shirt-sleeve

How to measure

  1. 1. Lay the sleeve flat with the cuff closed.
  2. 2. Start at the shoulder seam.
  3. 3. Measure along the outside edge to the cuff.

Common mistakes

  • xMeasuring from the collar
  • xStopping at the cuff seam
  • xLetting the sleeve bend under the tape

Why it matters: Sleeve length is a hard comfort check for cuffs, watches, and layering.

#shirt-length

How to measure

  1. 1. Keep the shirt face down.
  2. 2. Start where the collar band meets the back panel.
  3. 3. Measure straight to the longest point of the hem.

Common mistakes

  • xStarting at the top of the collar
  • xMeasuring the front instead of the back
  • xIgnoring a curved tail

Why it matters: Length decides whether the shirt works tucked, untucked, or layered.

Blazers, coats, truckers

Jackets

Jackets need relaxed fabric and careful seam selection because padding, lining, and lapels can distort the tape.

chestshoulder

Chest

Flat width from armpit to armpit with the jacket closed.

#jacket-chest

How to measure

  1. 1. Button or zip the jacket as it would be worn.
  2. 2. Smooth the body without pulling the lining tight.
  3. 3. Measure straight across at the pit seam.

Common mistakes

  • xMeasuring with the jacket open
  • xIncluding sleeve fabric
  • xPulling padded fronts taut

Why it matters: Chest determines whether the jacket closes and whether the front hangs cleanly.

#jacket-shoulder

How to measure

  1. 1. Turn the jacket face down.
  2. 2. Identify the sleeve head seam on each side.
  3. 3. Measure straight across the upper back.

Common mistakes

  • xIncluding shoulder padding overhang
  • xFollowing a curved seam
  • xMeasuring across the front lapels

Why it matters: Shoulder width is difficult to alter and drives the whole silhouette.

#jacket-sleeve

How to measure

  1. 1. Flatten the sleeve without forcing the elbow shape.
  2. 2. Start at the shoulder seam.
  3. 3. Measure to the cuff edge.

Common mistakes

  • xStarting at the collar
  • xMeasuring the inner sleeve
  • xIgnoring working button cuffs

Why it matters: Sleeves are alterable only within limits, especially on finished cuffs.

  3. 3. Measure straight to the hem.

Common mistakes

  • xStarting at the collar top
  • xUsing front length on a cutaway jacket
  • xMeasuring over folded vents

Why it matters: Length separates cropped casual jackets from classic tailoring proportions.

Trousers, denim, fatigues

Pants & Jeans

Bottoms compare best when the waistband, rise, and inseam are measured separately instead of trusting tagged waist size.

Waist

Flat waistband width measured edge to edge.

#pants-waist

How to measure

  1. 1. Fasten the waist closure.
  2. 2. Align front and back waistband edges naturally.
  3. 3. Measure straight across and double for circumference.

Common mistakes

  • xStretching elastic or denim
  • xMeasuring a dipped waistband unevenly
  • xForgetting to double flat width

Why it matters: Waist decides whether the garment can be worn without tailoring or belt compensation.

Inseam

Inside leg length from crotch seam to hem.

#pants-inseam

How to measure

  1. 1. Fold one leg so the inseam is visible.
  2. 2. Start at the crotch seam intersection.
  3. 3. Follow the inner seam to the hem edge.

Common mistakes

  • xMeasuring outseam instead
  • xStarting below the crotch seam
  • xIgnoring cuff allowance

Why it matters: Inseam determines break, crop, and whether hemming is enough to rescue the fit.

  3. 3. Measure to the top front waistband edge.

Common mistakes

  • xUsing back rise without labeling it
  • xStarting below the seam intersection
  • xPulling the fly into a curve

Why it matters: Rise changes where pants sit and how much room exists through the top block.

How to measure

  1. 1. Lay the leg flat with the inseam visible.
  2. 2. Start about one inch below the crotch seam.
  3. 3. Measure straight across to the outside leg edge.

Common mistakes

  • xMeasuring too far down the leg
  • xPulling pleats open
  • xComparing thigh width to circumference

Why it matters: Thigh room is the main comfort check for denim, fatigues, and tailored trousers.

Knits, cardigans, sweatshirts

Sweaters

Knitwear moves under tension, so measure relaxed and note whether the fabric has stretch, ribbing, or drop shoulders.

chestshoulderlength

Chest

Relaxed pit-to-pit width across the front of the knit.

#sweater-chest

How to measure

  1. 1. Lay the sweater flat and let ribbing relax.
  2. 2. Measure from pit to pit without stretching.
  3. 3. Record whether the knit is heavy, ribbed, or elastic.

Common mistakes

  • xStretching the knit while measuring
  • xIgnoring drop shoulders
  • xComparing shrunk wool to tagged size

Why it matters: Sweater chest controls drape and layering room more than the letter size does.

Sleeve

Sleeve length from shoulder seam, or from collar on raglan and drop-shoulder knits.

#sweater-sleeve

How to measure

  1. 1. Identify whether the sweater has set-in, raglan, or drop shoulders.
  2. 2. Measure from the clearest sleeve start point.
  3. 3. Note the start point in the measurement label.

Common mistakes

  • xTreating drop shoulders like set-in sleeves
  • xStretching ribbed cuffs
  • xHiding the measurement start point

Why it matters: Knit sleeve measurements need context because shoulder construction changes the number.

#sweater-length

How to measure

  1. 1. Let the hem ribbing relax.
  2. 2. Start at the back collar seam or high shoulder point.
  3. 3. Measure straight down without stretching the body.

Common mistakes

  • xPulling ribbing to gain length
  • xStarting at the top of the collar
  • xIgnoring cropped hems

Why it matters: Sweater length controls layering and whether ribbing lands at the waist or hip.

Sneakers, boots, loafers

Shoes

Shoes need both marked size and actual length context because brand lasts and international conversions vary.

lengthmarked size

Shoe Length

Interior or outsole heel-to-toe length when the seller provides it.

#shoe-length

How to measure

  1. 1. Record the marked size exactly.
  2. 2. Measure insole length when removable.
  3. 3. Use outsole length only when it is clearly labeled as outsole.

Common mistakes

  • xUsing outsole length as insole length
  • xConverting size systems without noting the source
  • xIgnoring toe shape

Why it matters: Length evidence makes tagged shoe sizes easier to compare across brands and lasts.

Shoe Width

Marked width letter or widest usable forefoot measurement.

#shoe-width

How to measure

  1. 1. Record any marked width letter.
  2. 2. If measuring, use the widest forefoot point.
  3. 3. Compare against a known comfortable pair from the same category.

Common mistakes

  • xIgnoring width letters
  • xMeasuring the sole edge instead of usable interior width
  • xComparing dress shoes and sneakers directly

Why it matters: Width often explains why the right length still feels wrong.

Note. Width is taken at the widest point — across the ball of the foot — not the toe cap or the heel.

Belts, hats, bags

Accessories

Accessories usually need one decisive usable dimension rather than a full garment profile.

Belt Length

Usable belt range from buckle prong to the adjustment holes.

#belt-length

How to measure

  1. 1. Start at the buckle prong, not the buckle end.
  2. 2. Measure to the tightest and loosest usable holes.
  3. 3. Record the range rather than total leather length.

Common mistakes

  • xMeasuring total belt length only
  • xIgnoring buckle allowance
  • xRecording only one hole

Why it matters: Accessory sizing fails when decorative length is confused with usable fit range.

Hat Circumference

Inside band circumference where the hat sits on the head.

#hat-circumference

How to measure

  1. 1. Measure around the inside sweatband.
  2. 2. Keep the tape level and relaxed.
  3. 3. Record inches or centimeters with the tagged size.

Common mistakes

  • xMeasuring outer brim width
  • xMixing diameter and circumference
  • xIgnoring adjustable closures

Why it matters: Hat fit depends on circumference, not brim or crown dimensions.

Bag Dimensions

Exterior width, height, and depth plus strap drop when relevant.

#bag-dimensions

How to measure

  1. 1. Measure width across the widest structured point.
  2. 2. Measure height and depth separately.
  3. 3. Add strap drop for shoulder and crossbody bags.

Common mistakes

  • xCombining depth with width
  • xIgnoring strap drop
  • xMeasuring collapsed soft bags inconsistently

Why it matters: Bag dimensions decide what actually fits inside and how the bag carries.

Note. All three dimensions are measured at the bag body — never the handles, straps, or opening flare.
