Master Zeplin & Sketch: 3 Pro Tips for Efficient UI Slicing and Handoff
This guide shows UI designers how to prepare Sketch files for Zeplin, create shared icon styles, and add exportable slices so developers can instantly access accurate measurements, assets, and naming conventions, streamlining the handoff process.
As a designer seeking efficiency, many have adopted Zeplin for its time‑saving annotation features; the updated version now supports Photoshop and offers powerful slicing capabilities.
When collaborating with Sketch, there are three practical tips to help developers read visual designs more easily.
1. Layout in Sketch for clearer Zeplin inspection
Design list items by first drawing a rectangle that defines the row height, then place text and images inside the same group, centering them vertically within the rectangle. After uploading to Zeplin, the tool automatically annotates row height, image size, and margins, giving developers the exact values they need.
2. Handling icons with different visual weight
Because icons vary in shape and size, equal physical spacing can look uneven. Create a shared style that defines a maximum icon container (e.g., a 30×30 px rectangle) and keep the outer spacing consistent. Adjust the icon lines carefully—avoid 0.5 px values to prevent fuzzy edges. Zeplin will then display clear measurements for each icon.
How to create the shared style
Create a rectangle (8‑10 px larger than the icon), no stroke, name it “bg”.
Establish the shared style using that rectangle.
Adjust opacity for easier icon inspection.
Press the “F” key to toggle fill visibility; the frame outline remains, helping you see the icon’s exact bounds.
3. Adding exportable slices directly in Sketch for Zeplin
Select the element to slice, click the “make exportable” button in the bottom‑right corner, then press the “+” icon to create a slice. The slice icon appears on the layer, and Zeplin will generate a downloadable asset with the correct dimensions.
Give each slice a clear name before exporting; Zeplin follows iOS naming conventions (camelCase) and developers can download the assets directly.
For oversized graphics like a glow that exceeds the artboard, create a mask using the “F” key to hide the fill, then slice only the visible portion.
By following these tips, designers can streamline the Zeplin‑Sketch workflow, reduce manual measurements, and deliver clean, ready‑to‑code assets.
