Methodology

How we measure: Size demand

Every figure in a Closo data block names its window and its source. This page says how each one is calculated and when we publish it. When the sample is too small, we say so instead of showing a number.

Size demand

Which sizes sell, and how fast?

What the figure is
A table of sizes with each size's share of sales and its median days to sell.
What it covers
One brand and one product type, optionally one segment.
Time window
Sales from the last 365 days.
When we publish it
Published when at least three sizes each have 50 or more sales.
Source
Sold listings on Poshmark collected by Closo.
How it is calculated
Sales of a size divided by all sales of the brand and product type; days to sell as for sell speed.

Prices on hub and lot pages are explained in How we price. Every other method is on How we measure. Past resale results do not promise future ones; prices and demand change.
