Pull the numbers the listing actually uses
Open the size chart on the product page and note the units. For sweaters: chest width, body length, sleeve length. For trousers: waist, rise, inseam, leg opening. For boots: ask whether a length is insole, outsole or a foot-length recommendation — those are not interchangeable.
Different shapes need different checks
On this sheet, the cream crewneck, grey quarter zip and black zip cardigan are not the same collar problem. Timberland six-inch and UGG short boots are not the same shaft problem. If you only compare “M” to “M”, you miss the part that usually causes returns.
Missing chart? Write “unknown”, do not guess
If chest or insole is blank, mark it unknown in your item record and ask before ordering. Guessing a letter “close enough” is how wrong sizes get locked in — QC photos rarely fix that later.
Compare several styles first when you are undecided
Choosing among crewnecks, a quarter zip and a cardigan? Open the knitwear guide. Choosing lace-ups, short boots or heels? Open the boots guide. Then return to the filtered spreadsheet to save links or download a CSV.

Common questions
Does every spreadsheet row include a size chart?
No. Charts live on the destination listing. We store fit notes and dated snapshots, not a full size table for every find.
Should I size up for knits or boots automatically?
Not from this page. Ask for the method, then compare with something that already fits.
Where are the sweater and boots side-by-side comparisons?
Knitwear guide and boots guide, then Categories or the spreadsheet filter to save links.
