# TransformWidth

```ts
type TransformWidth = typeof TRANSFORM_WIDTHS[number];
```

Defined in: packages/asset-client/src/transform.ts:52

A CDN-whitelisted transform width — the only widths `TransformOptions.width`
accepts. Off-ladder widths are a compile error; for signed URLs that need a
signature, use [getSignedTransformUrl](/api/nitida/asset-client/functions/getsignedtransformurl/) /
`aq.transform(asset, opts, { sign: true, expiresInSeconds })` — which names
the caller but does NOT widen the ladder.
