App Icon Size Calculator
Calculate app icon dimensions, aspect ratio, pixel area and scaled export dimensions. Choose a common icon size or enter your own dimensions to quickly check your icon size.
App Icon Size Calculator
Select a common icon size or enter custom width and height values.
The width and height are equal, producing a square icon.
What Is an App Icon Size Calculator?
An app icon size calculator helps you check the pixel dimensions of an icon before preparing it for an app, website, progressive web app, shortcut, favicon, or other digital interface.
Enter the width and height of an icon to calculate its aspect ratio, total pixel area, and scaled export dimensions. This makes it easier to check whether an icon has the intended proportions before exporting or uploading it.
How to Use the App Icon Size Calculator
- Choose a preset if one of the available sizes matches your needs.
- Enter the icon width in pixels.
- Enter the icon height in pixels.
- Select an export scale when you need a higher-density version.
- Click Calculate Icon Size to view the results.
How App Icon Size Is Calculated
The calculator uses your width and height values to determine several useful measurements.
Pixel Area
Pixel area is calculated by multiplying the width by the height.
Aspect Ratio
The aspect ratio compares the width and height after reducing both values by their greatest common divisor.
Scaled Export
The selected export scale multiplies both dimensions while keeping the same proportions.
Height × Scale
Common App Icon Sizes
These common dimensions are included as convenient presets in the calculator.
| Icon Type | Width | Height | Aspect Ratio |
|---|---|---|---|
| App Icon | 1024 px | 1024 px | 1:1 |
| Large Icon | 512 px | 512 px | 1:1 |
| Web App Icon | 192 px | 192 px | 1:1 |
| Touch Icon | 180 px | 180 px | 1:1 |
| Tablet Icon | 152 px | 152 px | 1:1 |
| Favicon | 32 px | 32 px | 1:1 |
Why Icon Dimensions Matter
Icons can appear at many different sizes across apps, websites and devices. Starting with suitable pixel dimensions helps preserve clarity and makes it easier to prepare multiple versions of the same design.
Square dimensions are common for application icons and many web icon formats. However, custom dimensions can also be useful for other digital graphics, which is why this calculator supports independent width and height values.
Pixel Dimensions vs File Size
Pixel dimensions describe the width and height of an image. File size describes how much storage the image file occupies. Two images with identical pixel dimensions can have different file sizes because of their format, compression, transparency, and image content.
This calculator focuses on pixel dimensions and related measurements. It does not calculate the final PNG, JPEG, WebP, SVG, or other image file size.
Frequently Asked Questions
What is the best size for an app icon?
There is no single size that applies to every platform. Icon requirements depend on where the icon will be used, so check the current specifications of the target platform.
What is the aspect ratio of a square app icon?
A square icon has a 1:1 aspect ratio because its width and height are equal.
How many pixels are in a 1024 × 1024 icon?
A 1024 × 1024 icon contains 1,048,576 pixels.
Can I calculate a custom app icon size?
Yes. Enter your own positive width and height values to calculate the dimensions, aspect ratio, pixel area, and scaled export size.
What does 2× export mean?
A 2× export doubles both the width and height in pixels while preserving the original aspect ratio.
Are app icons always square?
Many app and web icon formats use square dimensions, but other digital graphics can use different proportions. This calculator supports rectangular dimensions as well.
Does a larger icon always mean a larger file?
Larger pixel dimensions can contain more image data, but final file size also depends on the image format, compression, transparency, and image content.
