A lot of this question comes from mirroring. Someone casts a newer iPhone, like the iPhone 15 or 16, to an older Hisense TV. The picture shrinks into a narrow strip with black bars on each side.
Other times it's about cropping a video for Instagram, or wondering why a screenshot looks unusually tall. The math behind all of this is simple once you know your iPhone's actual ratio.
The 30-Second Aspect Ratio Test
You can skip the specs and check this fast. Does your iPhone have a Home button below the screen? If yes, it's a 16:9 screen — the same shape as most TVs and laptops. If no, meaning it has Face ID or a Dynamic Island, it's a taller 19.5:9 screen. That single detail explains most of what follows.
If you're here because a Hisense TV picture looks stretched after mirroring, jump to the fix below. If you've simply lost the remote and need the TV's picture settings, the free HiRemote app can help. It turns your iPhone into a full Hisense remote. That way you can open the settings menu without hunting for batteries.
Method 1: Match Your iPhone Model to Its Screen Aspect Ratio
Every iPhone falls into one of two groups. The table below shows which ratio your model uses, and what that means in practice.
| iPhone Group | Approx. Screen Ratio | What It Means |
|---|---|---|
| iPhone X through the current Pro, Pro Max, and standard lineup (Face ID or Dynamic Island) | 19.5:9 | Tall and narrow. Landscape video often needs black bars on a 16:9 TV. |
| iPhone SE (all generations) and older Home-button models (8, 8 Plus, 7, 7 Plus) | 16:9 | Close to standard TV and laptop shape. Less letterboxing when mirrored. |
| Plus and Pro Max sizes within the Face ID group | 19.5:9 | Bigger screen, same ratio as the smaller model in that group. |
Apple's iPhone comparison page lists exact screen size and resolution for every model, if you want the precise numbers.
Method 2: Spot Why This Matters for Mirroring, Video, and Design
A 19.5:9 screen is narrower than a 16:9 TV. When you mirror video shot at full screen width, some apps add black bars on the sides. This avoids stretching the picture. Other apps zoom in instead, which can crop the top and bottom. Neither result means something is broken. It's just two different shapes sharing one rectangle.
If mirroring itself is the problem, not just the ratio, our iPhone screen mirroring guide covers setup for every TV type. Photo and video editing hit the same clash. A photo shot at the iPhone's native ratio won't fill a square Instagram post, or a widescreen YouTube thumbnail, without some cropping.
Fix 1: Fix a Stretched or Letterboxed Picture When Mirroring to a TV
Start on the TV side. Open the picture settings. Look for anything related to aspect ratio, zoom, or screen size. TVs label this differently depending on brand and model, so check a couple of menus if the first one doesn't match. Switching away from a zoom or stretch mode usually clears up a stretched picture.
Next, rule out the source file. If the original video was shot in portrait mode, no TV setting fixes that. A vertical video will not fill a landscape screen cleanly. That's expected, not a bug. Our Hisense TV settings guide walks through the full picture menu, if you want more context.
Can't find the Hisense remote to even open that menu? The free HiRemote app pairs with your TV over Wi-Fi in 30 seconds. It gives you full directional-pad control from your phone. It also works as a browser-based remote for Roku-powered Hisense TVs at hiremote.app/hisense-roku-tv-remote — no install needed.
Fix 2: Export Photos and Video in the Right Ratio for Each Platform
Instagram Stories, Reels, and TikTok fill the screen best with a vertical 9:16 crop. A standard feed post works better as a square or a 4:5 crop. YouTube and most TVs expect landscape 16:9 content instead.
The Photos app on your iPhone has a built-in crop tool. It includes common ratio presets, like square and 16:9. You don't need a separate app for basic resizing. For anything more specific, like a brand template, a dedicated editing app gives you manual crop handles instead of fixed presets.
Frequently Asked Questions
What is the aspect ratio of an iPhone screen?
Most current iPhones have a 19.5:9 aspect ratio. That's a tall, narrow shape. It applies to every Face ID model, from the iPhone X through the newest Pro and Pro Max versions. Older iPhones with a Home button, plus both iPhone SE generations, use a shorter 16:9 ratio instead. The ratio affects how photos, video, and mirrored content fit other screens.
Do all iPhones have the same aspect ratio?
No, iPhones split into two groups. Face ID and Dynamic Island models use roughly 19.5:9. Home-button models, including the iPhone SE, use 16:9 instead. Screen size changes between models like the Pro and Pro Max. The ratio inside each group stays the same. Knowing your group matters more than knowing your exact model.
Why does my iPhone video look cropped or boxed on my TV?
Your iPhone usually records video close to 16:9, but the screen itself is 19.5:9. Playback apps sometimes add black bars to avoid stretching the image. A TV set to the wrong zoom mode can crop the edges further. Check the TV's aspect ratio setting first. Then confirm the original video wasn't filmed in portrait mode.
What aspect ratio should I use for Instagram or TikTok on iPhone?
Use a vertical 9:16 ratio for Instagram Stories, Reels, and TikTok. That fills the screen without black bars. Standard Instagram feed posts work better with a 4:5 or square crop instead. You can trim existing footage to these ratios with the Photos app's crop tool before uploading.
Is the iPhone screen ratio 16:9 or 19.5:9?
Both, depending on the model. Older Home-button iPhones and the iPhone SE use 16:9, the same ratio as most TVs. Every Face ID or Dynamic Island iPhone, from the iPhone X onward, uses the taller 19.5:9 ratio instead. If your iPhone has no Home button, it's 19.5:9.
How do I fix a stretched picture when mirroring an iPhone to a Hisense TV?
Open the TV's picture settings and look for anything related to aspect ratio, zoom, or screen size — the exact label varies by brand and model. Switching away from a stretch or zoom mode usually fixes it. If you can't find your Hisense remote, the free HiRemote app lets you navigate that menu over Wi-Fi from your phone instead.
