My iPhone Icons Are Large: What’s Happening?

The Zoom feature may be turned on

What to Know

• To zoom out to normal size, hold three fingers together and double-tap the screen with all three fingers at once.
• To turn off Zoom go to Settings >Accessibility >Zoom >Off.

This article explains the cause of large icons in iOS 12 and newer and how to correct them with the Zoom feature.

The Cause of a Zoomed-In iPhone Screen and Huge Icons

When the iPhone screen is magnified, the iPhone Zoom feature may have been accidentally turned on. Zoom is an accessibility feature that helps people with poor vision enlarge items on the screen to see the screen better.

When the iPhone screen is zoomed in, and your icons are too large, it could be a problem. In this situation, everything looks huge, and app icons fill the entire screen, making it hard or even impossible to see the rest of the apps. Even pressing the Home button doesn’t help. This problem isn’t as bad as it may seem, though. Fixing an iPhone with a zoomed-in screen is easy.

How to Zoom out to Normal Size on iPhone

To restore icons to normal size, hold three fingers together and double-tap the screen with all three fingers at once. This gesture returns the Zoom level to normal.

When in Zoom mode, follow the Rule of Three: A three-finger tap gesture to zoom in, a three-finger double-tap (plus a pinching drag gesture) to change the zoom, and drag three fingers to move around the screen. You’ll also find these tips in the Zoom menu in Settings.

How to Turn off Screen Zoom on iPhone

To prevent screen zoom from being accidentally turned on again, turn off the feature:

Tap the Settings app to open it.

In the General screen, tap Accessibility.

On the Accessibility screen, tap Zoom.

On the Zoom screen, turn off the Zoom toggle switch.

Check that the setting is working by double-tapping three fingers on the Home screen. If nothing happens, the Zoom feature was successfully disabled.

This procedure restores the iPhone to its normal magnification and prevents the enlargement from happening again.

What iOS Devices Are Affected by Screen Zoom

The Zoom feature is available on the iPhone 3GS and newer, the 3rd generation iPod touch and newer, and all iPad models.

If you have one of these devices and the icons are large, Zoom is the most likely culprit, so try these steps first. If they won’t work, something strange is going on. You may want to consult Apple directly for help.

Use Display Zoom and Dynamic Type to Improve Readability

While screen magnification makes it harder for some to see the iPhone screen, others may want icons and text to be a bit larger. There are a couple of features that enlarge text and other aspects of the iPhone to make them easier to read and use:

What size are iphone icons

The coordinate system iOS uses to place content onscreen is based on measurements in points, which map to pixels in the display. A standard-resolution display has a 1:1 pixel density (or @1x), where one pixel is equal to one point. High-resolution displays have a higher pixel density, offering a scale factor of 2.0 or 3.0 (referred to as @2x and @3x). As a result, high-resolution displays demand images with more pixels.

For example, suppose you have a standard resolution (@1x) image that’s 100px × 100px. The @2x version of this image would be 200px × 200px, and the @3x version would be 300px × 300px.

Supply high-resolution images for all artwork in your app, for all devices your app supports. Depending on the device, you accomplish this by multiplying the number of pixels in each image by a specific scale factor.

Device	Scale Factor
12.9″ iPad Pro	@2x
11″ iPad Pro	@2x
10.5″ iPad Pro	@2x
9.7″ iPad	@2x
7.9″ iPad mini 4	@2x
iPhone X S Max	@3x
iPhone X S	@3x
iPhone X R	@2x
iPhone X	@3x
iPhone 8 Plus	@3x
iPhone 8	@2x
iPhone 7 Plus	@3x
iPhone 7	@2x
iPhone 6s Plus	@3x
iPhone 6s	@2x
iPhone SE	@2x

Designing High-Resolution Artwork

Use an 8px-by-8px grid. A grid keeps lines sharp and ensures that content is as crisp as possible at all sizes, requiring less retouching and sharpening. Snap the image boundaries to the grid to minimize half pixels and blurry details that can occur when scaling down.

Produce artwork in the appropriate format. In general, use de-interlaced PNG files for bitmap/raster artwork. PNG supports transparency and, because it’s lossless, compression artifacts don’t blur important details or alter colors. It’s a good choice for intricate artwork that requires effects like shading, textures, and highlights. Use JPEG for photos. Its compression algorithm usually produces smaller sizes than lossless formats and artifacts are harder to discern in photos. Photo-realistic app icons, however, look best as PNGs. Use PDF for glyphs and other flat, vector artwork that requires high-resolution scaling.

Use the 8-bit color palette for PNG graphics that don’t require full 24-bit color. Using an 8-bit color palette reduces file size without reducing image quality. This palette is not appropriate for photos.

Optimize JPEG files to find a balance between size and quality. Most JPEG files can be compressed without noticeable degradation of the resulting image. Even a small amount of compression can save significant disk space. Experiment with compression settings on each image to find the optimal value that yields an acceptable result.

Provide alternative text labels for images and icons. Alternative text labels aren’t visible onscreen, but they let VoiceOver audibly describe what’s onscreen, making navigation easier for people with visual disabilities.

What size are iphone icons

You must provide an app icon to display on the Apple Watch Home screen and in various other contexts. If your watchOS app has an iPhone companion app, you must also supply a version of your app icon to display on the iPhone Home screen.

A watchOS app icon is circular and displays no accompanying text.

Embrace simplicity. Find a single element that captures the essence of your app and express that element in a simple, unique shape. Add details cautiously. If an icon’s content or shape is overly complex, the details can be hard to discern, especially at smaller sizes. Take advantage of the icon’s circular shape as part of your design.

Maintain some similarity between your watchOS and iOS app icons. Using a similar appearance and color palette creates an association between the two icons. They don’t need to be identical, but they should be recognizable together.

Provide a single focal point. Design an icon with a single, centered element that immediately captures people’s attention and clearly identifies your app.

Design icons as full-bleed square images using the given dimensions. Apple Watch automatically applies a circular mask. For guidance, see Icon Sizes.

Provide icons in PNG format. Make sure your icons are deinterlaced and without transparency. The standard image bit depth is 24 bits. Create all icons at 2x resolution. For guidance, see Icon Attributes.

Avoid using black for your icon’s background. Lighten a black background or add a border so that the icon doesn’t blend into the display background.

Avoid text in your icons. Text in icons is often too small, so avoid it when you can. However, using a mnemonic—such as the first letter of your app’s name—as a key design element in your icon can help people recognize your app.

If you have a companion app, maintain some similarity between your watchOS and iOS app icons. Using a similar appearance and color palette creates an association between the two icons. The watchOS and iOS icons don’t need to be identical, but they should be recognizably related.

Icon Attributes

All watchOS app icons should use the following specifications.

Attribute	Value
Format	PNG
Color space	Display P3 (wide-gamut color), sRGB (color), or Gray Gamma 2.2 (grayscale)
Layers	Flattened with no transparency
Resolution	@2x
Shape	Square (not rounded or oval)

Icon Sizes

Provide your app icon in the following sizes. For templates that help you create icons in these sizes, see Apple Design Resources.

What resolution should my iPhone App Icon be?

What image resolution can/should be used for the icon.png file for an iPhone app? I know the size is 57 x 57 but what about the resolution?

8 Answers 8

Resolution only matters when you are trying to match the size of an image across multiple devices (print, screen, etc)

App icons are always 57×57 and will display without any scaling thus resolution doesn’t matter (you could save it as 72dpi, 65535dpi or missing the dpi metadata entirely—SpringBoard won’t care and will draw it the same in all three cases)

Here is the link to Apple guidelines, with the sizes for iPad, iPhone retina, etc:

The «resolution» matters, but don’t confuse «resolution» with dpi. Dpi is a measure used for printing, it means «dots per inch». It works like this: if you have an image of 100 x 100 saved at 100dpi, it will measure on paper exactly 1 inch (100 pixels per inch).

The dpi for the icons doesn’t really matter, as they are intended for screen display only, not for printing.

It is customary to save images as 72dpi — the so called «screen resolution», because the old 14» monitors (remember those?) could only display a maximum of 72 pixels per every inch of screen. This is no longer true, especially for the «retina» display of the iPhone. It has a much denser screen resolution, it can show much more pixels in a single inch than the older models of the iPhone. This is why you have to save 2 icons: one for retina display at 114 x 114 pixels, and another for the older iPhones, at 57 x 57. Again, the dpi doesn’t matter, because whatever dpi you choose, the number of pixels on your image does not change: it would always have exactly 12,996 pixels (114 x 144).

What size are iphone icons

Every app needs a beautiful and memorable icon that attracts attention in the App Store and stands out on the Home screen. Your icon is the first opportunity to communicate, at a glance, your app’s purpose. It also appears throughout the system, such as in Settings and search results.

Embrace simplicity. Find a single element that captures the essence of your app and express that element in a simple, unique shape. Add details cautiously. If an icon’s content or shape is overly complex, the details can be hard to discern, especially at smaller sizes.

Provide a single focus point. Design an icon with a single, centered point that immediately captures attention and clearly identifies your app.

Design a recognizable icon. People shouldn’t have to analyze the icon to figure out what it represents. For example, the Mail app icon uses an envelope, which is universally associated with mail. Take time to design a beautiful and engaging abstract icon that artistically represents your app’s purpose.

Keep the background simple and avoid transparency. Make sure your icon is opaque, and don’t clutter the background. Give it a simple background so it doesn’t overpower other app icons nearby. You don’t need to fill the entire icon with content.

Use words only when they’re essential or part of a logo. An app’s name appears below its icon on the Home screen. Don’t include nonessential words that repeat the name or tell people what to do with your app, like «Watch» or «Play.» If your design includes any text, emphasize words that relate to the actual content your app offers.

Don’t include photos, screenshots, or interface elements. Photographic details can be very hard to see at small sizes. Screenshots are too complex for an app icon and don’t generally help communicate your app’s purpose. Interface elements in an icon are misleading and confusing.

Don’t use replicas of Apple hardware products. Apple products are copyrighted and can’t be reproduced in your icons or images. In general, avoid displaying replicas of devices, because hardware designs tend to change frequently and can make your icon look dated.

Don’t place your app icon throughout the interface. It can be confusing to see an icon used for different purposes throughout an app. Instead, consider incorporating your icon’s color scheme. See Color.

Test your icon against different wallpapers. You can’t predict which wallpaper people will choose for their Home screen, so don’t just test your app against a light or dark color. See how it looks over different photos. Try it on an actual device with a dynamic background that changes perspective as the device moves.

Keep icon corners square. The system applies a mask that rounds icon corners automatically.

App Icon Attributes

All app icons should adhere to the following specifications.

Attribute	Value
Format	PNG
Color space	Display P3 (wide-gamut color), sRGB (color), or Gray Gamma 2.2 (grayscale). See Color Management.
Layers	Flattened with no transparency
Resolution	Varies. See Image Size and Resolution.
Shape	Square with no rounded corners

App Icon Sizes

Every app must supply small icons for display on the Home screen and throughout the system when your app is installed, as well as a larger icon for display in the App Store.

Device or context	Icon size
iPhone	60×60 pt (180×180 px @3x)
60×60 pt (120×120 px @2x)
iPad Pro	83.5×83.5 pt (167×167 px @2x)
iPad, iPad mini	76×76 pt (152×152 px @2x)
App Store	1024×1024 pt (1024×1024 px @1x)

Provide different sized icons for different devices. Make sure that your app icon looks great on all the devices you support.

Mimic your small icon with your App Store icon. Although the App Store icon is used differently than the small one, it’s still your app icon. It should generally match the smaller version in appearance, although it can be subtly richer and more detailed because there are no visual effects applied to it.

Spotlight, Settings, and Notification Icons

Every app should also provide a small icon that iOS can display when the app name matches a term in a Spotlight search. Additionally, apps with settings should provide a small icon to display in the built-in Settings app, and apps that support notifications should provide a small icon to display in notifications. All icons should clearly identify your app — ideally, they should match your app icon. If you don’t provide these icons, iOS might shrink your primary app icon for display in these locations.

Device	Spotlight icon size
iPhone	40×40 pt (120×120 px @3x)
40×40 pt (80×80 px @2x)
iPad Pro, iPad, iPad mini	40×40 pt (80×80 px @2x)

Device	Settings icon size
iPhone	29×29 pt (87×87 px @3x)
29×29 pt (58×58 px @2x)
iPad Pro, iPad, iPad mini	29×29 pt (58×58 px @2x)

Device	Notification icon size
iPhone	20×20 pt (60×60 px @3x)
20×20 pt (40×40 px @2x)
iPad Pro, iPad, iPad mini	20×20 pt (40×40 px @2x)

Don’t add an overlay or border to your Settings icon. iOS automatically adds a 1-pixel stroke to all icons so that they look good on the white background of Settings.

TIP If your app creates custom documents, you don’t need to design document icons because iOS uses your app icon to create document icons automatically.

User-Selectable App Icons

For some apps, customization is a feature that evokes a personal connection and enhances the user experience. If it provides value in your app, you can let people select an alternate app icon from a set of predefined icons that are embedded within your app. For example, a sports app might offer icons for different teams or an app with light and dark modes might offer corresponding light and dark icons. Only users can choose one of the alternate app icons you supply, and the system always provides confirmation when people make this change.

Provide visually consistent alternate icons in all necessary sizes. Like your primary app icon, you deliver each alternate app icon as a collection of related images that vary in size. When people choose an alternate icon, the system replaces your primary app icon with the appropriately sized alternate icon on the Home screen, in Spotlight, and elsewhere in the system. To ensure that alternate icons appear consistently throughout the system, provide them in the same sizes you use for your primary app icon.

For developer guidance, see the setAlternateIconName method of UIApplication.

NOTE Alternate app icons are subject to app review and must adhere to the App Store Review Guidelines.
