The Trusted Standard for Clothing Condition Grading
GradeThread gives every pre-owned garment an objective 1.0–10.0 condition grade and a certificate buyers can verify — one published rubric, applied the same way every time, so a grade means the same thing everywhere. Cut returns, sell faster, and run the whole reselling workflow in FlipDesk.

Why GradeThread is the standard
GradeThread is the standard for pre-owned clothing condition because a grade here is objective, published, reproducible, and independently verifiable — not one more seller's opinion.
Objective
Every garment is scored against one rubric — five weighted factors on a fixed 1.0–10.0 scale — not a subjective, seller-by-seller eyeball judgement.
Published
The factors, their fixed weights, and the seven named tiers are disclosed up front — the rubric is open to inspect, not hidden in a black box.
Reproducible
Because the rubric and weights are fixed, two items in the same condition earn the same grade — regardless of who submits them or when.
Independently verifiable
Every grade becomes a public certificate buyers can open and check, and we publish our measured accuracy against expert reviewers.
See the full grading standard and our published accuracy report.
Every grade ends in a certificate buyers trust
This is exactly what your buyers see: an overall score, a tier, the five weighted factor scores, and a verifiable badge you can drop straight into any listing. Scannable, shareable, and backed by one published standard.
- Objective 1.0–10.0 score with a plain-language tier
- Transparent factor-by-factor breakdown
- A scannable badge for eBay, Poshmark, Mercari, Depop & Grailed
