iPhone App Icon Calculator
Generate required iPhone icon sizes from one master design. Built for quick App Store and Xcode asset prep.
Custom Point-to-Pixel Calculator
Why an iPhone icon calculator matters
Designing an app icon is one part creativity and one part precision. On iPhone, icons are defined in points and exported in multiple pixel densities (@2x and @3x). That means one visual can quickly become several required files. An icon calculator removes manual math and helps you export exactly what Apple expects.
If you are a solo founder, UI designer, or iOS developer, this saves time and prevents common submission errors such as missing sizes, wrong dimensions, or inconsistent naming.
Standard iPhone icon sizes (quick reference)
For iPhone app targets, you will usually need these point sizes and scales:
- Notification: 20pt at @2x and @3x (40px, 60px)
- Settings: 29pt at @2x and @3x (58px, 87px)
- Spotlight: 40pt at @2x and @3x (80px, 120px)
- App icon: 60pt at @2x and @3x (120px, 180px)
- Marketing/App Store: 1024px square
Even if you work from a 1024×1024 master icon, the final deliverable is a full icon set that supports all display contexts cleanly.
How to use this calculator
1) Set your base master size
Use 1024px if your icon is App Store ready. If your current source is different, enter that size to see relative scaling percentages.
2) Generate the iPhone icon set
Click the generate button to receive a complete table including point size, scale, pixel result, and suggested filename patterns. This is useful when exporting from Figma, Sketch, Photoshop, or Illustrator.
3) Use custom point conversion when needed
If you are building a custom component or checking a design spec, use the point-to-pixel mini calculator. It instantly computes px from a pt + scale pair.
Best practices for iPhone app icons
- Start from a high-quality 1024×1024 master file.
- Keep shapes bold and readable at tiny sizes (40px/58px).
- Avoid text unless absolutely necessary; it rarely scales well.
- Export as PNG and verify every output dimension.
- Let iOS handle mask/rounding behavior—don’t hard-bake unusual clipping unless required by your brand guidelines.
Common mistakes this tool helps prevent
- Submitting only one icon size and forgetting smaller variants.
- Confusing points with pixels during handoff from design to dev.
- Using inconsistent export names across versions.
- Assuming @2x files are enough for all modern iPhones.
FAQ
Do I need @1x icons for modern iPhone apps?
Typically no for iPhone-only targets. Most workflows require @2x and @3x, plus the App Store marketing icon. Always verify current requirements in Apple’s latest Human Interface Guidelines and Xcode asset catalog prompts.
Can I use this for iPad too?
This version is tuned for iPhone. You can still use the custom point calculator for iPad specs, but add iPad-specific point sizes (including 83.5pt) when building a full universal icon set.
What is the safest source size?
1024×1024 is the practical standard source size because it covers the largest requirement and scales down cleanly for every smaller output.
Pro tip: after exporting, drag all generated files into your Xcode asset catalog and confirm there are no warning badges before shipping.
