How to Resize Layers

Different layer types in AppMockUp Studio use different resizing methods to ensure consistent results across all screenshot sizes. Learn how to resize each type of layer and understand why different approaches are used.

Resizing on the Canvas

Select a layer, a sticky or a highlight on the canvas and drag one of its edge handles. Each layer type resizes the way its controls do: icons and images in pixels, text layers by width only, devices and highlights by scale.

• Hold Shift to lock the aspect ratio.
• Drag a corner handle to round the corners; the radius is shown beside the handle. Corner handles appear where rounding is visible: on icons and images, on highlights and stickies, and on a device with its frame hidden.
• Hold Shift to step the radius in tens, or Alt to round a single corner instead of all four.
• On an Instance Screenshot, hold Ctrl/Cmd while dragging to save the change for that device only.

Resizing Icons

Icons use pixel-based dimensions for precise sizing control, making it easy to match specific size requirements and maintain consistent proportions.

Controls available:

• Width input and slider (in pixels)
• Height input and slider (in pixels)
• Maintain aspect ratio lock toggle

Pro Tips:

• Enable aspect ratio lock when you want to maintain proportions while resizing
• Pattern icons follow the same resizing rules as regular icons

Resizing Text Layers (Titles and Subtitles)

Text layers use percentage-based width to ensure consistent sizing across different screenshot dimensions. Height is automatically calculated based on content and text properties.

Key features:

• Width control using percentages (1-100%)

• Automatic height calculation based on:

• Text content

• Font size

• Line height

Why Percentages?

Using percentages ensures that text layers maintain consistent proportions relative to the screenshot width, regardless of the device size or aspect ratio. This approach makes it easier to maintain a cohesive look across your entire screenshot set.

Resizing Devices and Screen Captures

Devices and screen captures use a scale-based approach to maintain their fixed aspect ratios while allowing size adjustments.

Applies to:

• Device layers with frames
• Screen captures without frames
• Highlights (pop-outs) of screen captures

Why Scale?

Scale-based resizing is ideal for elements with fixed aspect ratios, like devices and screenshots. It ensures that the content always maintains its proper proportions while making it easy to synchronize sizes across different screenshots.

Understanding Different Resizing Methods

While having different resizing methods might seem complex at first, each approach is optimized for its specific layer type:

• Icons (Pixels): Perfect for matching exact size requirements and maintaining crisp visuals
• Text (Percentages): Ensures consistent proportions across all screenshot sizes
• Devices (Scale): Maintains aspect ratios while allowing unified size adjustments

Keyboard Shortcuts

Use these shortcuts for precise size adjustments:

↑ / ↓- Increment/decrement by 1

Shift + ↑ /↓ - Increment/decrement by 10
