You can adjust the photo size on Galaxy S10, S10e, S10 5G, and S10+ to make sure the photo is good for the intended usages, e.g., to show on a TV screen, or to print on photopapers, or to use it for a design project.
Unfortunately, Samsung removed the option to explicitly set photo size on Galaxy S10, S10e, S10 5G, and S10+. You have to implicitly set photo size through the aspect ratio settings.
This Galaxy S10 camera guide explains the available photo sizes and how to set photo size on Galaxy S10, S10e, S10 5G, and S10+
Why you may want to set photo size on Galaxy S10, S10e, S10 5G, and S10+?
The requirement for a photo to be shared with others on the phone or to be printed on the photobook is surely different.
The size of a photo includes two factors:
- Aspect ratio.
- The number of pixels (resolution).
For the aspect ratio, the Galaxy S10 camera supports the following aspect ratios: 4:3, 16:9, 1:1, and 19:9 (full), as explained in Galaxy S10 camera settings.
The 4:3 aspect ratio is good for printing and for old monitors. The native aspect ratio of the rear camera sensors on all Galaxy S10 phones is close to 4:3.
Therefore, among all aspect ratios, the 4:3 aspect ratio can have the maximum pixels. You can imagine photos with all other aspect ratios are just cropped from the 4:3 one (as illustrated in the picture below).
The 16:9 aspect ratio is ideal for most TV screens and modern monitors.  Because of 4:3=16:12, a 16:9 photo crops the 4:3 photo in the height direction and maintains the width.
The 1:1 aspect ratio is mostly used by designers and some social networks. As 1:1=3:3, a 1:1 photo on Galaxy S10 crops the 4:3 photo in the width direction and maintains the height.
The 19:9 (aka full) ratio matches the Galaxy S10 phone screen. All 4 Galaxy S10 models have a screen with an aspect ratio of 19:9. A 19:9 photo on Galaxy S10 also crops the 4:3 photo in the height direction and maintains the width, like the 16:9 one.
The cropping relationship between the 4 aspect ratios is illustrated in the following picture.
Please note, the above discussion is only for the rear cameras on Galaxy S10.
The front camera(s) on Galaxy S10 has a native aspect ratio close to (slightly smaller than) 3:2. This means for aspect ratios larger than 3: 2 (i.e., 19:9 and 16:9), the photos are cropped in the height direction. The photos with an aspect ratio smaller than 3:2 (i.e., 4:3 and 1:1) are cropped in the width direction.
For some unknown reasons, Samsung removed the options to set up the number of pixels for the photos on Galaxy S10. Once you set the aspect ratio, the size of the photo will be fixed at the maximum number of pixels.
How to set photo size on Galaxy S10, S10e, S10 5G, and S10+?
On Galaxy S10, you only need to choose the aspect ratio to set up the photo size. There are no separate settings for the number of pixels.
As shown in the screenshot below, once you open the camera app on Galaxy S10, you can find the aspect ratio button. Tap the button to choose one of the 4 aspect ratios.
Please note, for videos, one aspect ratio may have more than one size (resolution). You need to set the video size in Galaxy S10 camera settings.
Some Galaxy S10 camera modes, e.g., the newly added night camera mode, can only use the 12MP wide-angle camera.
What are the available photo sizes on Galaxy S10, S10e, S10 5G, and S10+?
As mentioned, the photo size on Galaxy S10, S10+, S10e, and S10 5G is fixed at the maximum pixels with each aspect ratio.
In other words, once you set the aspect ratio, the number of pixels will also be set automatically on Galaxy S10 phones.
The following table summarizes available photo sizes of all cameras on Galaxy S10, S10e, S10 5G, and S10+.
Table 1. Supported photo sizes on Galaxy S10, S10e, S10 5G, and S10+
| Phone | 1:1 | 4:3 | 16:9 | 19:9 | |
| 16MP Ultra-wide (rear) | All | 3456×3456 | 4608×3456 | 4608*2592 | 4608×2184 |
| 12MP Tele (rear) | except for S10e | 3024×3024 | 4032×3024 | 4032×2268 | 4032×1908 |
| 12MP Wide-angle (rear) | All | 3024×3024 | 4032×3024 | 4032×2268 | 4032×1908 |
| 10MP Selfie (front) | All | 2736×2736 | Â 3648*2736 | Â 3968*2232 | 3968×1880 |
| 8MP RGB Depth (front) | S10+ | 2208×2208 | 2944×2208 | 3216×1808 | 3216×1528 |
All: All Galaxy S10 phones (S10, S10+, S10e, and S10 5G)
Photo size is in the number of pixels of width x height (in the landscape orientation).
How about video size on Galaxy S10?
As explained in Galaxy S10 camera settings, Galaxy S10 supports 3 aspect ratios for videos: 16:9, 1:1 and 19:9.
You can change the resolution of the 16:9 videos in camera settings. On the Galaxy S10 camera app interface, when you change the aspect ratio, the resolution you set for the 16:9 video will be used automatically.
