Why GradeThread is the standard
GradeThread is the standard for pre-owned clothing condition because a grade here is objective, published, consistently applied, 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.
Consistent
Every grade uses the same fixed rubric and weights — the same five factors, scored the same way, whoever submits the item. Not a seller-by-seller eyeball judgement.
Independently verifiable
Every grade becomes a public certificate buyers can open and check, and we publish an open accuracy report — updated as review volume grows.
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
