How to Design Accessible UI for Low Vision Players

Accessible UI for low vision players—using scalable text, high contrast, and adequate size—lets players with low vision read and use the interface, serving players who'd otherwise struggle. Providing text scaling and contrast options and ensuring adequate sizing is a meaningful accessibility investment that helps a significant population of players.

Scalable text and high contrast serve low vision players

Players with low vision struggle with UI that's small or low-contrast, so two key accommodations serve them: scalable text and high contrast. Scalable text means letting players increase the text size—a text scaling option that lets players make the UI text larger—so players with low vision can read text that would be too small at the default size, which is essential because small text is a primary barrier for low vision players, and scalable text lets them set a readable size. High contrast means ensuring (or offering an option for) strong contrast between text and background and between UI elements—so the UI is readable for players with low vision or contrast sensitivity, who struggle with low-contrast UI where text and elements blend into backgrounds. Providing high contrast (or a high-contrast option) makes the UI readable for these players. Scalable text (letting players enlarge text to a readable size) and high contrast (making text and elements stand out clearly) serve low vision players by addressing the primary barriers they face—small text and low contrast—letting them read and use the UI. These accommodations are key to UI accessibility for low vision, addressing the size and contrast barriers that otherwise exclude these players.

Adequate size and accessibility options complete accessible UI for low vision. Beyond scalable text and high contrast, ensuring adequate default size and providing accessibility options complete accessible UI for low vision. Adequate size means the UI is reasonably sized by default—not so small that it's a struggle even for players with normal vision, and a reasonable baseline for accessibility—because an adequately-sized default UI is more accessible than a tiny one, even before scaling. Ensuring adequate default sizing (readable, reasonably-sized UI) provides a good baseline, on top of which scaling helps further. Providing accessibility options means offering the options (text scaling, contrast, and other accessibility settings) that let players tune the UI to their needs, since different low vision players need different accommodations, and options let each player set what works for them. Accessibility options (text scaling, high contrast, and others) let players with varying low vision needs tune the UI to be readable and usable for them, which is more inclusive than a one-size-fits-all UI. This connects to accessibility generally: providing options that let players accommodate their needs serves the range of players. Combining scalable text and high contrast (the key accommodations addressing the size and contrast barriers low vision players face) with adequate size and accessibility options (a good default baseline and options to tune to individual needs) is what makes UI accessible for low vision players. By providing scalable text, high contrast, adequate default sizing, and accessibility options, the UI becomes readable and usable for players with low vision, who'd otherwise struggle with small, low-contrast UI. Designing accessible UI for low vision—scalable text, high contrast, adequate size, accessibility options—is a meaningful accessibility investment that serves a significant population of players (low vision is common) who'd otherwise struggle to read and use your UI, letting them enjoy your game. This both includes these players (an accessibility and inclusion benefit) and expands your audience (more players can use the UI), as discussed in accessibility benefits generally. Provide scalable text, high contrast, adequate size, and accessibility options, and your UI serves low vision players, letting them read and use the interface that small, low-contrast UI would exclude them from. Accessible UI for low vision is a worthwhile investment that helps a significant population of players read and use your game.

Trust behaviour over opinions

People are unreliable narrators of their own experience — they're polite, they rationalise, they suggest fixes that miss the real problem. What they do tells the truth that what they say obscures: where they hesitate, where they get stuck, what they ignore, where they quit. The most valuable feedback is usually the behaviour you observe, not the opinion you're offered.

This is why watching beats asking, and why real data about what players actually do beats any amount of speculation. When several people stumble at the same spot, that's a problem worth fixing, regardless of whether any of them mentioned it.

Ship it, then learn from it

No amount of internal deliberation substitutes for the information you get the moment real players touch your game. The assumptions that felt certain turn out wrong, the feature you doubted becomes the favourite, and the problem you never imagined is the one everyone hits. That feedback only exists on the other side of shipping.

So bias toward getting something real in front of real people sooner rather than later. A rough thing that's out in the world teaches you more in a week than another month of private refinement, and every release makes the next decision better informed.

Cut the feature, keep the focus

The instinct to add is far stronger than the instinct to remove, which is exactly why most games drift toward bloat rather than clarity. Every system you add has to be built, balanced, debugged, and maintained, and it competes for the player's attention with everything else. A focused game that does a few things excellently almost always beats a sprawling one that does many things adequately.

When you're tempted by one more feature, ask what it costs and what it competes with, not just what it adds. The discipline to keep a game focused is what lets the parts that matter shine, and it's usually the difference between a memorable game and a forgettable one.

The player doesn't see what you see

You know where to click, which path works, and what every system is supposed to do, because you built it — and that knowledge makes you the worst possible judge of how your game reads to someone encountering it fresh. The confusion you can't feel is exactly the confusion that costs you players.

This is why fresh eyes are so valuable and so uncomfortable: they reveal the gap between the game in your head and the game on the screen. Put your work in front of people who've never seen it, watch where they stumble, and treat that stumble as information rather than as their mistake.

Default to the boring, robust choice

It's tempting to reach for the clever, novel, or technically impressive solution, but in production the boring choice — the well-understood approach, the proven pattern, the simple implementation — is usually the one that ships and keeps working. Cleverness has a way of becoming the bug you're debugging at 2am six months later.

Save your novelty budget for the things that actually make your game distinctive, and be conservative everywhere else. A game built on robust, unremarkable foundations is one you can keep building on, while one built on clever fragility is one that fights you the whole way.

Accessible UI for low vision uses scalable text, high contrast, adequate size, and accessibility options—so players with low vision can read and use the interface. It's a meaningful investment that serves a significant population of players who'd otherwise struggle with small, low-contrast UI.
