# Prints

> Choose an immutable print size and submit prepared portrait or landscape artwork.

Prints are one public product family. Each physical size remains an immutable
variant because its dimensions, price, provider mapping, and revision can
change independently.

| Product ID    | Physical output | Accepted artwork |
| ------------- | --------------- | ---------------- |
| `print-4x5`   | 4 × 5 inches    | `4:5` or `5:4`   |
| `print-4x6`   | 4 × 6 inches    | `2:3` or `3:2`   |
| `print-5x5`   | 5 × 5 inches    | `1:1`            |
| `print-5x7`   | 5 × 7 inches    | `5:7` or `7:5`   |
| `print-3.5x5` | 3.5 × 5 inches  | `7:10` or `10:7` |
| `print-8x10`  | 8 × 10 inches   | `4:5` or `5:4`   |
| `print-12x18` | 12 × 18 inches  | `2:3` or `3:2`   |
| `print-16x20` | 16 × 20 inches  | `4:5` or `5:4`   |

All print variants use revision `1`. Their `artwork` role allows rotation, so
the prepared dimensions determine portrait or landscape orientation. Batch
Relay validates the ratio and does not crop the image to make it fit.

```json theme={null}
{
  "product": { "id": "print-5x7", "revision": 1 },
  "quantity": 1,
  "options": [{ "option_id": "paper", "value": "lustre" }],
  "assets": [{
    "role": "artwork",
    "url": "https://cdn.example.com/orders/team-5x7.jpg",
    "pixel_width": 2000,
    "pixel_height": 2800
  }]
}
```

Paper choices are `lustre`, `pearl`, and `deep-matte`. Read the matching
catalog `unit_costs` entry and its `pricing_status`; a `null` amount means the
provider price is unverified. In particular, `print-3.5x5` remains unavailable
for hosted quoting until Batch Relay verifies its provider cost.
