Step by Step Tutorial on How to Type in All Caps on iPhone

Before we get started with the steps, it’s important to note that what we’re about to cover will enable you to type in all caps continuously. Let’s jump in.

Step 1: Open the Keyboard

Open any app that lets you type, such as Messages, Notes, or Mail.

When you open an app where you can type text, the keyboard will automatically appear on the screen. If it doesn’t, tap on the text field to bring it up.

Step 2: Double-Tap the Shift Key

Quickly double-tap the shift key (the up arrow) on your keyboard.

Upon successfully double-tapping the shift key, you’ll notice it turns blue, or on some devices, it shows a line beneath the arrow. That’s your visual cue that Caps Lock is active.


EmphasisTyping in all caps can be a way to emphasize a word or phrase in a text.
ProfessionalismIn professional settings, it’s often necessary to use all caps for certain terms or titles.
AccessibilityFor those with visual impairments, all-caps can be easier to read.

Emphasis in text communication can be tricky, but capital letters can make it clear when you’re making an important point. It’s like raising your voice in a conversation – it grabs attention.

In professional documents or emails, there are instances where it’s standard to use all caps, such as legal documents or certain headings. Knowing how to quickly switch to all caps can save time and maintain the format required.

For individuals with visual impairments, text in all caps can be easier to discern. The uniform size of uppercase letters can create a more readable text block, which can be helpful in various scenarios.


PerceptionUsing all caps can sometimes be perceived as shouting.
AestheticsOveruse of all caps can make the text hard on the eyes and less aesthetically pleasing.
Accidental ActivationIt’s possible to accidentally enable Caps Lock, leading to unintended capitalization.

While emphasis is good, too much of it can backfire. In digital etiquette, typing in all caps is often akin to shouting, which can come off as aggressive or rude if not used carefully.

A wall of text in all caps can be jarring and less inviting to read. It can also come off as less professional in certain contexts, making it important to use this feature judiciously.

Sometimes, in the heat of typing, you might accidentally double-tap the shift key and not realize you’ve activated Caps Lock. This can lead to sending messages or documents with unintended all-caps sections, which can be embarrassing or unprofessional.

Additional Information

When it comes to typing on your iPhone, the little things can make a big difference. Knowing how to quickly toggle Caps Lock can be a game-changer for speed and efficiency. But did you know that you can also customize your keyboard settings? For instance, you can adjust the key click sounds or even add different language keyboards.

Another tip for avid typists is to explore the text replacement feature in iOS 17. This lets you create shortcuts for phrases you type often. For example, “omw” can automatically expand to “On my way!” – saving you precious seconds.

Remember, while typing in all caps can be useful, it’s also important to be mindful of how it’s perceived. Use it when necessary, but don’t overdo it. Typing in all caps can be impactful, but it’s the digital equivalent of shouting, so use it sparingly and appropriately.
