How to Measure Clothing for Accurate Listings (Reseller Guide)
Inaccurate measurements are the #1 cause of INAD (Item Not As Described) returns on eBay and Poshmark. Every return costs you shipping, fees, and rating damage. Five minutes of measuring prevents all of this.
Essential Measurements
Pit to Pit (Chest)
Lay the garment flat, buttoned/zipped. Measure straight across from armpit seam to armpit seam. This is THE most important measurement for tops. Buyers double this number to get the full chest circumference.
Length
Tops: From the highest point of the shoulder (where the seam meets the collar) straight down to the hem.
Dresses: Same starting point, down to the bottom hem.
Pants: From the top of the waistband to the bottom of the leg opening (outseam).
Inseam (Pants)
From the crotch seam straight down to the bottom of the leg opening. This is what determines "short," "regular," or "long" fit.
Waist
Lay pants flat, measure straight across the top of the waistband. Double for full waist measurement. Note: vanity sizing means the tagged size often doesn't match the actual measurement. Always include the actual measurement.
Rise (Pants)
From the crotch seam straight up to the top of the waistband. Low rise = under 9". Mid rise = 9-10.5". High rise = over 10.5".
Shoulder to Shoulder
From one shoulder seam to the other, measured across the back. Important for structured items like blazers and jackets.
Measuring Tools
A soft measuring tape is essential — rigid rulers don't follow curves. Lay items on a flat, clean surface (not a bed, which creates wrinkles). For consistency, measure the same way every time.

Poshmark: Include measurements in the description AND photograph them (lay the tape on the garment, snap a photo). Poshmark buyers expect measurement photos.
eBay: Fill in the item specifics for measurements if available. Include in description as backup. Detailed measurements reduce INAD rates and the 6% penalty for below-average metrics.
Mercari: Include in description. Mercari doesn't have dedicated measurement fields, so put them prominently in the first few lines.
