iPad screen resolution and aspect ratios can vary
When viewing a presentation on certain iPads, black bars may appear on the sides of the presentations.
This is because for iPad, presentations are scaled to a 4:3 aspect ratio, which is the most common aspect ratio for iPads.
Here is the list of iPads where you will see black bars when presenting:
| iPad | Aspect Ratio |
| iPad Mini 6 (2021) | 3:2 |
| iPad Pro 11″ (2018-2022) | 10:7 |
| iPad 10 (2022) | 23:16 |
| iPad Air 4 (2020) | 23:16 |
| iPad Air 5 (2022) | 23:16 |
