# Mac desktop too small or letterboxed on your iPad? Causes and fixes

> Why your Mac screen looks tiny with black bars over remote desktop on an iPad – with the resolution of every iPad model and four fixes.

## In short

- The remote app shows your Mac’s monitor. It’s usually 16:10 or 16:9, while the iPad is about 4:3 to 3:2 – that’s where the bars come from.
- If the monitor has more space than the iPad, everything shrinks: a 2560 × 1440 desktop appears at about 54% size on a 13-inch iPad Pro.
- Fixes: change the Mac’s resolution by hand, zoom in the app, or switch the desktop to the iPad’s shape and resolution with PadTailor.
- PadTailor does this with one switch in the menu bar and restores your displays afterwards.

You connect to your Mac from your iPad over remote desktop – and everything is tiny, with black bars at the top and bottom. It isn’t your app and it isn’t the connection. It comes down to two numbers: **aspect ratio** and **area**.

## Cause 1: the aspect ratio doesn’t match

A remote desktop app streams whatever the Mac shows on its monitor. MacBooks are about 16:10, most external monitors 16:9. iPads are much squarer. When the app fits the wide picture into the iPad, part of the iPad screen stays empty.

How much of the iPad’s height is lost with a 16:10 or 16:9 desktop:

| iPad | Resolution (pixels) | Aspect ratio | Bars at 16:10 | Bars at 16:9 |
| --- | --- | --- | --- | --- |
| iPad Pro 13″ (M4, M5) | 2752 × 2064 | 4:3 | 17% | 25% |
| iPad Air 13″ (M2–M4), iPad Pro 12.9″ (1st–6th gen.) | 2732 × 2048 | 4:3 | 17% | 25% |
| iPad Pro 11″ (M4, M5) | 2420 × 1668 | 1.45:1 | 9% | 18% |
| iPad Pro 11″ (1st–4th gen.) | 2388 × 1668 | 1.43:1 | 11% | 20% |
| iPad Air 11″ (M2–M4), iPad Air (4th/5th gen.), iPad (10th gen., A16) | 2360 × 1640 | 1.44:1 | 10% | 19% |
| iPad mini (6th gen., A17 Pro) | 2266 × 1488 | 1.52:1 | 5% | 14% |

So on a 13-inch iPad with a 16:9 monitor, a quarter of the screen stays black.

## Cause 2: the Mac desktop is bigger than the iPad

Area matters even more. iPads use double pixel density (Retina 2×): a 13-inch iPad Pro with 2752 × 2064 pixels equals 1376 × 1032 points of workspace. A 27-inch monitor at 2560 × 1440 points is almost twice as wide. To fit it onto the iPad, the app shrinks everything to about **54%**. On an iPad mini (1133 × 744 points) it’s only around **44%**.

The result: menus, text and buttons are roughly half their usual size – and hard to hit with a finger.

## Fix 1: change the Mac’s resolution by hand

Under **System Settings → Displays** you can choose a lower resolution. That makes the desktop bigger, but has downsides:

- macOS only offers resolutions the **connected monitor** supports. A shape like 4:3 usually isn’t one of them, so the bars remain.
- The monitor at the Mac then looks blurry or distorted.
- You have to change it before every session and switch back afterwards – ideally before you leave.

## Fix 2: zoom in the remote app

Most apps can switch between “fit to screen” and actual size, or zoom with a pinch. That makes details readable, but you only ever see part of the screen and keep scrolling around. Fine for quick tasks, tedious for longer work.

## Fix 3: configure a virtual display by hand

General-purpose display tools can create virtual displays at any resolution. That gets you there, but you have to work out the right resolution for your iPad yourself, mirror the display, and undo everything after the session.

## Fix 4: PadTailor – built for exactly this

[PadTailor](https://padtailor.app/en/) automates fix 3 for remote desktop on an iPad:

1. Pick your **iPad model** from the list once. Every model in the table above is included.
2. Choose one of **four interface sizes** – from “Larger controls” to “Maximum space”.
3. Before the session, turn on **“iPad display”** in the menu bar.

PadTailor then creates a virtual display with your iPad’s exact shape and Retina resolution and mirrors the Mac desktop onto it. Your remote app streams this desktop to the iPad. The interface size you choose determines your workspace; presentation and scaling also depend on your client. After the session you switch it off, and your displays are back to how they were.

While iPad display is on, all Mac displays show the same desktop in the iPad’s shape. That’s intentional: at the Mac you see exactly what arrives on the iPad.

You can try PadTailor free for 14 days with your remote app. It runs on Macs with Apple silicon and macOS 14 or later.

## Frequently asked questions

### Why does my Mac screen have black bars on my iPad?

Because the aspect ratios don’t match. Mac screens are usually 16:10 or 16:9, iPads between about 4:3 and 3:2. When the remote app fits the wider picture into the iPad, bars remain at the top and bottom.

### What resolution does my iPad have?

The 13-inch iPad Pro (M4/M5) has 2752 × 2064 pixels, the 11-inch iPad Pro (M4/M5) 2420 × 1668, the 13-inch iPad Air and 12.9-inch iPad Pro 2732 × 2048, the 11-inch iPad Air, iPad (10th generation) and iPad (A16) 2360 × 1640, and the iPad mini (6th generation, A17 Pro) 2266 × 1488 pixels.

### Can I just set my Mac’s resolution to match the iPad?

Only partly. Under System Settings → Displays, macOS only offers resolutions the connected monitor supports – iPad shapes are usually not among them. You also have to switch back after every session.
