One-handed keyboards and reachability

A six-inch display and one free hand don't mix — without help. You're holding a coffee cup, a bag of groceries, or a kid in your other arm, and you still need to type a message or dismiss a notification. But your thumb physically can't reach the opposite corner of a big display, no matter how hard you stretch. Luckily, both major platforms thought about this problem and have built-in fixes.

A typical scenario

David commutes with his kid in his arms and holds his phone in his other hand the whole way, needing to reply to messages along the way. A keyboard spread across the full width of the display means he simply can't reach the top row of letters or buttons in the corner — he has to keep repositioning the phone or risk dropping it. Anyone holding groceries, a subway pole, or who just has smaller hands than the phone's display demands runs into the same problem.

Once he turned on Gboard's one-handed keyboard, the whole keyboard shrank and slid over to the edge of the display, exactly where his thumb comfortably reaches. Similarly, Reachability on iPhone pulls the entire top half of the screen down, so even notifications in the top bar suddenly sit within reach of one thumb.

How to do it

1. Gboard (Android): hold down the Enter key (or the comma key, depending on the version) — a one-handed keyboard icon appears. Use the arrow in the menu to slide it to whichever edge matches the hand you type with.
2. iOS Reachability: a light swipe down along the very bottom edge of the screen (or a double-tap on the Home button on older models) pulls the whole screen down into the bottom half of the display, so you can reach the top elements with your thumb.
3. iOS one-handed keyboard: hold down the globe icon (or the emoji icon, if you don't have a globe key) on the keyboard and pick the compressed keyboard, left- or right-aligned, from the menu.
4. Try both variants (left/right) to see which matches the hand you usually hold your phone with — it isn't always your dominant hand. It can even vary for left- and right-handers depending on whether their other hand happens to be full at the moment.
5. On big phones, it's worth turning these modes into a lasting habit rather than an occasional fix — once the gesture becomes familiar, you'll reach for it automatically whenever your other hand is busy.
6. Try combining both approaches depending on the situation: the one-handed keyboard for typing messages, Reachability for reaching buttons and notifications outside the keyboard — each solves a different part of the problem.

The best tools

• Gboard one-handed mode — a free built-in feature, works on most Android phones.
• iOS Reachability — a built-in system feature independent of any particular keyboard, works system-wide, not just while typing.
• iOS one-handed keyboard — built directly into the system keyboard, nothing extra to install.
• Samsung One-Handed Mode — on Samsung phones, it also shrinks the entire system screen, not just the keyboard, into a corner of your choice.
• Accessibility touch controls (Android) — some manufacturers let you customize gestures for quickly switching between apps one-handed too, beyond just shrinking the keyboard.

What you get out of it

• Comfort: your phone stays usable even with one hand tied up by a bag, a kid, or a cup.
• Safety: less risk of dropping the phone while stretching a thumb across the whole display.
• Speed: typing one-handed with a repositioned keyboard is comparably fast to typing with both hands, not just an emergency workaround.
• Less frustration: no more repositioning your phone from hand to hand because of an unreachable corner of the screen.
