# Resize an image to 1.91:1 aspect ratio.

Drop your photos and download them in the 1.91:1 aspect ratio. Each photo keeps all its pixels at their own size; padding is added on the short side until the shape is 1.91:1, so nothing is cropped, enlarged or reduced. It runs in your browser; nothing is uploaded.

## From a phone photo to 1.91:1.

Common 12-megapixel phone photo shapes brought to 1.91:1: the size of the downloaded file and the padding added on each side (↔ left + right, ↕ top + bottom). The photo keeps its own pixels, so the output size follows the photo. The tool above uses the same calculation.

| Phone photo | Output size | Padding |
| --- | --- | --- |
| 4,032 × 3,024 · 4:3 | 5,776 × 3,024 px | ↔ 872 + 872 px |
| 3,024 × 4,032 · 3:4 | 7,701 × 4,032 px | ↔ 2,339 + 2,338 px |
| 4,032 × 2,268 · 16:9 | 4,332 × 2,268 px | ↔ 150 + 150 px |
| 2,268 × 4,032 · 9:16 | 7,701 × 4,032 px | ↔ 2,717 + 2,716 px |
| 3,024 × 3,024 · 1:1 | 5,776 × 3,024 px | ↔ 1,376 + 1,376 px |

## 1.91:1, answered.

**Which platforms ask for the 1.91:1 aspect ratio?**

Google Ads, LinkedIn ads, Microsoft Advertising, Amazon Ads, Nextdoor Ads, and Taboola. The table on this page gives each rule in full and links to the platform's guide.

**What size is the image after resizing to 1.91:1?**

It depends on the photo: its pixels stay and padding is added until the shape is 1.91:1. A 4,032 × 3,024 px phone photo becomes 5,776 × 3,024 px, with 872 px of padding on the left and 872 px on the right.

**Is the photo scaled or cropped when resizing to 1.91:1?**

Neither. The photo keeps every pixel at its original size and the padding colour fills the added area, so the whole product stays in frame and a small photo is not blurred by enlarging.
