Here’s a quick guide on how to expand line stroke in Adobe InDesign:

‍

To expand a line stroke in Adobe InDesign, draw a line using the 'Line' Tool, then select it with the Selection Tool to activate its properties.
Once selected, go to the Stroke panel and increase the Weight by choosing a higher value.
Notice how the line stroke thickens and visually expands along its shape.

📌 Why this matters

Expanding strokes gives you precise control over line thickness for creating visual hierarchy and emphasis in your designs. When you increase stroke weight, you're essentially converting thin, delicate lines into bold design elements that can anchor layouts or create separation between content areas.

This technique becomes especially powerful when working with complex illustrations or technical diagrams where certain pathways or borders need to stand out. Thicker strokes also improve readability in printed materials and ensure important linear elements remain visible when designs are scaled down for different applications.
