7 Proven Polygonal Lasso Tool in Photoshop Tricks for Clean Selections

What is the Polygonal Lasso Tool in Photoshop?

The polygonal lasso tool in Photoshop is one of the easiest selection tools for working with straight edges. If you’ve ever tried cutting out buildings, boxes, screens, or geometric shapes, this tool will quickly become your best friend.

Unlike the regular Lasso Tool, which lets you draw freely, the polygonal lasso tool works by creating straight-line segments. You click from point to point, and Photoshop connects them with straight lines. It’s perfect for objects without curved edges.

If you’re new to Adobe Photoshop, this tool is a great starting point before moving on to more advanced selection methods.

When Should You Use the Polygonal Lasso Tool?

Use it when:

• The object has clear angles.
• You need fast manual control.
• Automatic selection tools fail.

Avoid it when:

• The edges are soft.
• The object has hair or fur.
• You need ultra-detailed curves.

In those cases, other Photoshop tools might be more effective.
