+Various visual settings are available to players from the Roblox and in‑experience **Settings** menus, including [preferred transparency](#preferred-transparency), [preferred text size](#preferred-text-size), and [reduced motion](#reduced-motion). For optimal accessibility, your [user interface](../../ui/index.md) should accommodate each.
 
 ### Preferred transparency
 
-The in-game **Settings** menu contains a **Background Transparency** adjuster which maps to the `Class.GuiService.PreferredTransparency` property. A value of `1` indicates the player prefers the default background transparency, while a value of `0` indicates the player prefers fully opaque (non‑transparent) background transparency for improved readability and contrast.

A value of `1` indicates the player prefers the default background transparency, while a value of `0` indicates the player prefers fully opaque (non‑transparent) background transparency for improved readability and contrast.
 
 Multiplying a UI element's `Class.GuiObject.BackgroundTransparency|BackgroundTransparency` with `Class.GuiService.PreferredTransparency|PreferredTransparency` is the recommended way to use this setting; backgrounds will become more opaque as `Class.GuiService.PreferredTransparency|PreferredTransparency` approaches `0`.

+### Preferred text size
+
+The **Text Size** setting maps to the `Class.GuiService.PreferredTextSize` property which defaults to `Enum.PreferredTextSize.Medium|Medium`. Players can choose to increase text size through the engine's font rendering pipeline to `Enum.PreferredTextSize.Large|Large`, `Enum.PreferredTextSize.Larger|Larger`, or `Enum.PreferredTextSize.Largest|Largest`.
+
+When working with UI elements, note the following behaviors:
+
+- Text that is constrained to a minimum and/or maximum size through a `Class.UITextSizeConstraint` will **not** shrink below or expand above the set `Class.UITextSizeConstraint.MinTextSize|MinTextSize`/`Class.UITextSizeConstraint.MaxTextSize|MaxTextSize`, regardless of the player's text size setting.
+
+- When `Class.TextLabel.TextScaled|TextScaled` is enabled for a `Class.TextLabel.TextScaled|TextLabel` or `Class.TextButton.TextScaled|TextButton`, the element's text will **not** be scaled by the `Class.GuiService.PreferredTextSize|PreferredTextSize` value.
+
+- UI elements with `Class.GuiObject.AutomaticSize|AutomaticSize` enabled will shrink/grow as `Class.GuiService.PreferredTextSize|PreferredTextSize` decreases/increases (element bounds will resize to fit the resized text).
+
+- When `Class.TextLabel.TextWrapped|TextWrapped` is enabled for a `Class.TextLabel.TextWrapped|TextLabel` or `Class.TextButton.TextWrapped|TextButton`, the element's text will wrap to additional lines as `Class.GuiService.PreferredTextSize|PreferredTextSize` increases, within limits of the element's absolute size.
+
+- The results returned by `Class.TextService:GetTextSize()` and `Class.TextService:GetTextBoundsAsync()` honor changes related to `Class.GuiService.PreferredTextSize|PreferredTextSize`.
+
 ### Reduced motion
 
-The in-game **Settings** menu and Roblox app contains a **Reduce&nbsp;Motion** option which maps to the `Class.GuiService.ReducedMotionEnabled` property. A value of `true` indicates the player wants motion effects through [UI&nbsp;animations/tweens](../../ui/animation.md) to be reduced or completely removed.
+The **Reduce&nbsp;Motion** toggle maps to the `Class.GuiService.ReducedMotionEnabled` property. A value of `true` indicates the player wants motion effects through [UI&nbsp;animations/tweens](../../ui/animation.md) to be reduced or completely removed.
 
 A basic approach to removing motion from UI tweens is to set the `Datatype.TweenInfo.Time|Time` parameter of a `Datatype.TweenInfo` to `0` when `Class.GuiService.ReducedMotionEnabled|ReducedMotionEnabled` is `true`, effectively making the UI object snap to its target instantly.

 Different sounds playing at the same time can be overwhelming, distracting, or difficult to distinguish. Providing users with volume controls for different "groups" of audio such as sound effects, music, and speech lets them customize their experience and focus on what they need to.
