How the ASOS size estimate works
SizeWise filters the workbook rows to ASOS, then narrows results by fit category, garment type, region and fit type. The calculator scores your measurements against available ranges and shows a closest size with nearby alternatives when sizes are close.
Supported ASOS categories
ASOS is listed as UK in the workbook. Size recommendations are estimates and should be checked against product-level measurements where available.
ASOS size calculator FAQ
Quick answers for using this independent ASOS size guide.
How do I estimate my ASOS size?
Measure the body areas that matter for the garment, such as bust or chest, waist, hips, inseam or foot length. Then use this ASOS size calculator to compare those measurements with workbook size ranges.
Is this an official ASOS size calculator?
No. SizeWise is independent and is not affiliated with ASOS unless stated otherwise. Results are measurement-based estimates, not guarantees.
Can I convert ASOS sizes between UK, US and EU labels?
Yes. Where the workbook includes regional labels, the calculator can compare ASOS UK, US, EU and international size systems for supported garment categories.
Will this guarantee the right ASOS size?
No. The calculator gives a closest-size estimate. Product cuts, fabrics and product-level measurements can vary, so check the specific item before buying.
