Quick Answer
Keep the text short, high-contrast and clear of the clock, widgets and controls. Add it to a cropped photo with Markup in the Photos app, then set the photo from Settings > Wallpaper > Add New Wallpaper. If the text changes often, an app that writes your notes into the wallpaper saves redoing it all. NoteWall, our app, does that; a subscription is required.
Where should text go on an iPhone Lock Screen?
Leave clear space for everything that already lives on the Lock Screen. Apple's Create a custom iPhone Lock Screen guide lists a clock whose font you can change, widgets, and controls such as the flashlight, all drawn over your wallpaper. Text you add competes with each of them, so decide where your words will sit before choosing a photo.
Two details in that guide matter for layout. The clock can be made taller: Apple says to touch and hold the Lock Screen, tap Customize, then drag the clock's bottom right corner to increase its height. Widgets are optional and can be added or changed later by tapping Add Widgets. Design for your busiest Lock Screen, not the emptiest.
- •
One block, not scattered lines: a single group of text is easier to keep clear of the clock and widgets.
- •
Find a quiet area first: pick a photo with a calm patch, such as sky, wall or water, and put the text there.
- •
Leave a margin around the clock: a taller clock needs more room than the default.
- •
Check layered photos: Apple's guide lists a Depth Effect for photos that support layering; if you use it, look at how the layers sit against your text.
How do you make wallpaper text readable?
Make the text contrast strongly with whatever sits directly behind it. The best-known yardstick is the W3C's web accessibility guideline of at least 4.5:1 for normal text, which also works as a rule of thumb for wallpaper. After contrast, a larger size, short lines and a calm background do most of the work.
W3C WCAG 2.2, Success Criterion 1.4.3 Contrast (Minimum), which asks for at least 4.5:1 for normal text and 3:1 for large-scale text. It is a web accessibility guideline; we use it here only as a rule of thumb for wallpaper text.
Wallpaper adds a twist the web rule does not cover: the background is a photo, so contrast changes across the image. Judge it against the busiest patch behind your words, not the average.
- •
Color: light text on a dark area or dark text on a pale one. Mid-tone on mid-tone is the usual failure.
- •
Size: Markup has a size tool, as Apple's guide lists. Go larger than looks necessary on the editing screen, because a Lock Screen is read at a glance.
- •
Line length: a few short lines beat a paragraph.
- •
Background: a plain or softly varying area, not a detailed one.
NoteWall's FAQ gives the same advice from the other side. If your notes do not show up well, it asks whether the background is too busy and suggests trying the black or gray preset.
What size should the image be?
Start with a portrait photo and crop it in Photos rather than hunting for pixel dimensions. Apple's crop tool offers preset ratios that include Wallpaper and 9:16, and the Lock Screen editor lets you zoom and drag the picture into place. None of the Apple guides cited here lists pixel sizes, so this post does not either.
In Photos, Apple's crop guide says to open a photo, tap the edit button, then crop to a standard preset ratio and choose an option such as Square, Wallpaper, 9:16 or 5:7. Then, when you set the wallpaper, the Lock Screen guide covers repositioning: pinch open to zoom in, drag the image with two fingers to move it, then pinch closed to zoom out.
How do you add the text?
Add it with Markup in the Photos app, then set the finished photo as your wallpaper. This uses only built-in Apple tools and suits text you will not change often: a quote, a name, a goal for the year. The steps paraphrase Apple's Markup guide and wallpaper guide, plus the crop guide above.
- 1
Crop the photo.
In the Photos app, open the photo, tap the edit button, open the crop tool and choose a preset ratio such as Wallpaper or 9:16. Tap Done to save.
- 2
Open Markup.
If you do not see the Markup toolbar, Apple says to tap its icon or Markup.
- 3
Add a text box.
In the Markup toolbar, tap the add button, then tap Add Text.
- 4
Type and style.
Tap the text box, type with the keyboard, then use the tools for font, size, justification, style and color. Tap outside the text box when you are done, then close the toolbar.
- 5
Start a new wallpaper.
Open Settings, tap Wallpaper, tap Add New Wallpaper, then tap Photos at the top of the wallpaper gallery and pick your photo.
- 6
Position it.
Pinch open to zoom in, drag the image with two fingers to move it, then pinch closed to zoom out.
- 7
Apply it.
Tap Add, then choose Set as Wallpaper Pair to use it on the Lock Screen and Home Screen, or Customize Home Screen to treat the Home Screen separately.
For the full walkthrough and a comparison of the two approaches, see our guide on how to add text to iPhone wallpaper. Once it is set, lock your iPhone and check the text against the clock and any widgets you use.
What if the text changes often?
A photo with text baked in is fixed, so every change means editing the image and setting it again. For a weekly to-do list or reminders that rotate, an app that builds the wallpaper from notes you type is less work. NoteWall, our app, does this, and it is not the only one, though setup takes some patience.
Disclosure: NoteWall is our app. It is listed on the App Store as Lock Screen Notes: NoteWall, from seller Karol Billik, and it writes the notes you type into your Lock Screen wallpaper. Because iOS does not let apps change the wallpaper directly, an Apple Shortcut called Set NoteWall Wallpaper applies it. NoteWall is iPhone only and needs iOS 17.0 or later. According to its FAQ:
- •
Setup: install the Set NoteWall Wallpaper shortcut, add your notes, choose a wallpaper background, allow the permissions, then generate and apply. The FAQ puts it at about 2 minutes.
- •
Changes: edit a note and tap Update Wallpaper, about 5 seconds by the FAQ's count.
- •
Capacity: typically 3-8 notes fit, depending on length, and the app warns you if a note will not fit.
- •
Widgets: setup asks whether you use Lock Screen widgets so notes do not overlap them; you can change that later in Settings → Wallpaper Settings.
- •
Beyond notes: the app also has reminders, habits and streaks.
The Shortcut step is the fiddly part for many people; the FAQ says to tap Allow for every permission it asks for. A subscription is required, and the App Store shows the terms before you pay. If you would rather start from the notes side, see how to put a note on your iPhone Lock Screen.
Other apps do similar jobs. Going by today's US App Store listings, LockScreenNotes (Takumi Banjoya, Productivity) describes itself as an app that displays a note on your lock screen, and 3minders - Lock Screen Notes (Alexandr Moscaliuc, Graphics & Design) is built around keeping three reminders on your lock screen.
Frequently Asked Questions
Is NoteWall free?
No. NoteWall requires a subscription, and the App Store shows the terms before you pay. The Photos app and its Markup tools cost nothing extra, so the Markup method above needs no additional app.
How much text fits on a Lock Screen wallpaper?
The Apple guides cited here set no limit on text you add yourself, so the real limit is readability and the space around the clock and widgets. In NoteWall, typically 3-8 notes fit depending on length, and the app warns you if a note will not fit.
Why can't I read my notes in NoteWall?
NoteWall's FAQ suggests two checks. Is the background too busy? Try the black or gray preset. Are the notes too long? The app fits as many notes as possible, but very long notes might not all fit.
