A measurement checklist without a fit promise
Use measurements to understand an object accurately. The checklist is a document check, not a prescription for a body.
Record named dimensions
Write the exact model and version, then total length, usable length and the widest section. Note where each number was measured. If a seller supplies only an approximate label, mark it unknown and request a specification rather than guessing.
Include non-headline details
Record the handle or base, taper, curves, rigidity and control placement. Check intended use and care. For anal use, a retrieval safeguard is a design requirement; it cannot be inferred from length or from an attractive photo.
Compare like with like
Convert units consistently and compare the same measurement points. Do not use a circumference figure as a diameter. Keep a source link with the record. The result describes differences between objects, while comfort and symptoms need individual attention.

Before you decide
Are my numbers genuinely comparable, and which shape details are still missing?
