Accessibility in elementary OS: High Contrast and Large Text
A readable desktop can make a major difference to comfort, confidence and independence. In elementary OS, two of the most useful visual accessibility tools are High Contrast and Large Text. They can help people with low vision, age-related sight changes, eye strain, colour-contrast difficulties or simply a preference for a clearer interface.
These settings are built into the desktop rather than added through a separate accessibility application. That makes them easy to test, adjust and switch off when necessary. The exact names and placement can vary slightly between elementary OS releases, so a current installation may present the controls differently from an older guide or screenshot.
This guide explains what each option changes, where to find it, how it affects everyday applications and which additional settings can produce a more comfortable setup. The examples are relevant whether the computer is a compact laptop used in a Melbourne flat, a family desktop in Brisbane or a larger monitor in a home office in Perth.
Finding The Visual Accessibility Settings
Open the Applications menu and launch System Settings. Depending on the elementary OS version, visual controls are grouped under Accessibility, or under a closely related desktop and appearance category. Look for switches labelled High Contrast and Large Text.
High Contrast changes the visual separation between interface elements. It can make buttons, labels, panels and selected items easier to distinguish, particularly when a standard theme uses subtle grey tones. Large Text increases the size of supported interface text without requiring you to change the display resolution.
Turn on one option at a time and spend a few minutes using the desktop. This makes it easier to identify which setting is helping. You can also leave the Settings window open while testing the Applications menu, the dock, window controls and a few common programs.
The controls apply to the desktop session and generally remain active after you close System Settings. If a setting does not appear to affect a particular programme, that is usually a compatibility limitation rather than a fault with your computer.
What High Contrast Changes
High Contrast is designed to make visual boundaries and foreground elements easier to identify. Text should stand out more clearly from its background, while controls such as buttons, toggles and selected menu items receive stronger visual definition. This can be helpful when a standard elementary OS theme feels elegant but too restrained.
The result is not the same as simply choosing a darker wallpaper or turning the screen brightness up. Contrast concerns the difference between nearby colours and tones. A bright screen may still contain pale text on a light background, while a high-contrast theme can make those elements more distinct at a lower brightness level.
High Contrast may not change every application in the same way. Programmes that use the system’s GTK interface components are more likely to follow the desktop preference. Some browsers, games, Electron applications and software with its own custom interface can retain their original colours.
Web content is especially variable. A website can use fixed colours, images containing text or accessibility-unfriendly design that overrides the desktop appearance. In those cases, browser zoom, a reader mode or an extension may be needed alongside the elementary OS setting.
Making Large Text Work Well
The Large Text option increases the size of interface text across much of the desktop. Menus, application labels, dialog messages and system controls should become easier to read while the screen keeps its normal resolution. This is preferable to lowering the resolution, which can make the entire display look soft or reduce the available workspace.
Large Text is useful on high-density laptop screens, where default fonts may appear small even when the display is sharp. It can also help when a user sits further away from a monitor or needs to reduce visual fatigue during long sessions. A 13-inch laptop used on a train between Sydney and Wollongong may benefit from a different scale than a 27-inch home monitor.
There are trade-offs. Larger labels can cause some buttons to wrap, push controls onto a second line or make small application windows feel crowded. Well-designed software should adapt, but older applications may assume that text will remain at its default size.
When an application has its own text-size setting, use it for fine control. A web browser may offer page zoom, while a terminal may provide a font selector and a text size control. These local settings are often more precise than changing the entire desktop for a single programme.
Choosing The Right Combination
High Contrast and Large Text solve different problems. High Contrast helps you separate objects and read boundaries; Large Text increases the physical size of words. Many people benefit from using both, while others find that one option is sufficient.
| Setting | Main benefit | Areas most likely to change | Common limitation |
|---|---|---|---|
| High Contrast | Stronger separation between text, controls and backgrounds | Desktop panels, menus, GTK applications | Custom-themed apps and some websites may ignore it |
| Large Text | Bigger labels and interface wording | System Settings, menus, dialogs and supported apps | Some windows may become crowded |
| Browser zoom | Larger web pages and online text | Websites, webmail and documentation | Each site or browser profile may need separate adjustment |
| Display scaling | Enlarges more of the desktop interface | High-resolution screens and graphical controls | Reduces the amount of content visible at once |
Start with High Contrast if the main problem is distinguishing inactive controls, selected items or pale text. Start with Large Text if the words are clear but physically too small. Enable both when reading and identifying controls are equally difficult.
The best setting can change with lighting and location. Bright Australian daylight through a north-facing window may make reflections more noticeable, while evening use under warm indoor lighting can make low-contrast text harder to separate. Adjusting the screen position, reducing glare and choosing a comfortable brightness level can support the software changes.
Improving Apps That Ignore Desktop Preferences
A desktop accessibility setting cannot force every programme to follow the same rules. Web browsers are a common example. Use the browser’s zoom command to enlarge a page, and check whether it offers a minimum font size or a setting that prevents websites from using fonts below a preferred size.
Text-heavy applications often provide their own controls. In a terminal, increase the font size and choose a typeface with clear character shapes. In a document editor, adjust the zoom level for reading while leaving the document’s actual print size unchanged. File managers may provide an icon-size selector that is separate from the Large Text preference.
Flatpak applications can behave differently from software installed through the system’s usual packaging channels. Their interface toolkit, theme support and permissions may affect how they respond to desktop settings. Updating the application is worthwhile, since accessibility support can improve between releases.
If a particular application remains difficult to use, check for a built-in dark mode, font setting, zoom command or high-contrast theme. For web services used by Australian organisations, including online banking, Medicare-related services or university portals, browser zoom and the site’s own accessibility options may be more reliable than the desktop preference alone.
Supporting Settings For Easier Reading
Visual accessibility works best as a group of small adjustments. Reduce Motion can make animated transitions less distracting or uncomfortable. Reduce Transparency can give panels and overlays a more solid background, improving legibility over changing wallpaper or content.
A setting that dims inactive windows may help focus, but it can also make background information harder to read. If you frequently switch between windows, test this option carefully. The useful choice is the one that reduces confusion without hiding important context.
Screen magnification is another option when larger text is not enough. A magnifier can enlarge a small region of the display while leaving the rest at normal scale. This is useful for inspecting a diagram, reading a status indicator or working with a detailed map without making every window permanently larger.
A screen reader serves a different purpose from visual enlargement. It reads interface content aloud and can be valuable for users who cannot comfortably read the display. Keyboard accessibility features, such as Sticky Keys or Slow Keys, may also help users who find simultaneous key presses difficult. These tools can be considered separately from High Contrast and Large Text, since each addresses a different access need.
Checking Common Desktop Tasks
After changing accessibility settings, test the tasks you perform most often. Open the Applications menu, launch System Settings, browse a folder, connect to Wi-Fi and open a document. Check whether labels remain visible, whether selected items are obvious and whether buttons still fit inside their windows.
Pay attention to the dock and panel. Large text may make application names or system indicators occupy more space. On a small laptop, the available room can become tight, particularly when several applications are open. On a large monitor, the same change may feel comfortable and leave ample space.
Test notifications and dialog boxes as well. Important warnings should be readable without moving the window or guessing which button is selected. If a dialogue becomes cramped, enlarge the window if possible, use the application’s own scaling control or temporarily disable Large Text while completing that task.
It is also worth checking an external display. A setup that works well on a 24-inch monitor may feel oversized on a laptop, while a laptop setting may be insufficient on a 4K monitor. Australian users connecting a notebook to a television or office display should test both screens rather than assuming one scale will suit every situation.
Keeping The Setup Comfortable Over Time
Accessibility preferences should be treated as practical working settings, not permanent declarations about how a computer must look. Vision, lighting, workload and screen distance can change. You may prefer Large Text while reading documentation and a smaller layout when arranging a spreadsheet.
Keep a note of the settings that work for you, especially after an operating system upgrade. Major elementary OS releases can reorganise System Settings or refine the appearance controls. If an option seems to have disappeared, use the Settings search feature and check the release documentation before assuming that it has been removed.
When buying a monitor or laptop locally, look beyond resolution. A high-resolution panel with poor viewing angles, aggressive glare or tiny default scaling may be less comfortable than a slightly lower-resolution matte display. Australian retailers such as JB Hi-Fi, Officeworks and specialist computer shops often display screens in bright showroom lighting, so check specifications and return policies rather than judging readability from a brief glance.
The main lesson is simple: High Contrast improves separation, Large Text improves size, and application-specific zoom fills the gaps. Use them together when needed, test the result in real daily tasks and remember that the most accessible elementary OS desktop is the one that makes reading, selecting and working feel clear.
