However, With the Scale Factor setting in the Canvas Scaler, a constant scaling can be applied to all UI elements in the Canvas. This is also the default functionality of the Canvas when no Canvas Scaler is attached. Using the Constant Pixel Size mode, positions and sizes of UI elements are specified in pixels on the screen. If the 'Reference Pixels Per Unit' is set to 1, then the 'Pixels Per Unit' setting in the sprite will be used as-is.įor a Canvas set to 'Screen Space - Overlay' or 'Screen Space - Camera', the Canvas Scaler UI Scale Mode can be set to Constant Pixel Size, Scale With Screen Size, or Constant Physical Size. If a sprite has this 'Pixels Per Unit' setting, then one pixel in the sprite will cover one unit in the world.
The amount of pixels per unit to use for dynamically created bitmaps in the UI, such as Text. Settings for World Space Canvas (shown when Canvas component is set to World Space): Property: If a sprite has this 'Pixels Per Unit' setting, then its DPI will match the 'Default Sprite DPI' setting. The pixels per inch to use for sprites that have a 'Pixels Per Unit' setting that matches the 'Reference Pixels Per Unit' setting. The DPI to assume if the screen DPI is not known. The physical unit to specify positions and sizes in. Settings for Constant Physical Size: Property: Scale the canvas area with the width as reference, the height as reference, or something in between.Įxpand the canvas area either horizontally or vertically, so the size of the canvas will never be smaller than the reference.Ĭrop the canvas area either horizontally or vertically, so the size of the canvas will never be larger than the reference.ĭetermines if the scaling is using the width or height as reference, or a mix in between.

Settings for Scale With Screen Size: Property: If a sprite has this 'Pixels Per Unit' setting, then one pixel in the sprite will cover one unit in the UI. Scales all UI elements in the Canvas by this factor. Settings for Constant Pixel Size: Property: Makes UI elements retain the same physical size regardless of screen size and resolution. Makes UI elements bigger the bigger the screen is.
Makes UI elements retain the same size in pixels regardless of screen size. This scaling affects everything under the Canvas, including font sizes and image borders.ĭetermines how UI elements in the Canvas are scaled. The Canvas Scaler component is used for controlling the overall scale and pixel density of UI elements in the Canvas.
