Hacoo Size Guide

For tops and jackets

Record shoulder width, chest width, sleeve length and back length. If you plan to layer clothing underneath, compare with a jacket that already fits that way.

For pants and shorts

Compare waist, rise, inseam and leg opening. Confirm whether the listed waist is a flat width, a full circumference or a range for an elasticated waistband.

For footwear

Record foot length using a repeatable method, then read the exact model chart. Foot length, removable insole length and outsole length are different quantities. Follow the chart's stated method rather than adding a universal allowance or assuming regional conversions are exact.

Use the same measurement method

A comparison is only useful when both items are measured between the same points. Keep garments flat without stretching, record whether widths need to be doubled and note any elastic range separately.

Allow for ease and intended fit

Body measurements and garment measurements are not interchangeable. A fitted T-shirt, relaxed hoodie and layered jacket need different amounts of room, so compare with an item that already has the silhouette you want.

Choose the measurement method for the category

A number is useful only when its unit, endpoints and meaning are known. For shoes, keep foot length, insole length and outsole length separate. For a hoodie, distinguish flat chest width from body circumference and check whether sleeve length starts at the shoulder or neck. Comparing incompatible methods creates a false match even when the numbers look close.

Use the Hacoo shoe size comparison for a chart-reading example and the hoodie size guide for chest, length and layering checks. Each uses clearly labeled illustrative measurements rather than claiming a universal size conversion.
