While it may seem simple on the surface, knowing the ins and outs of the Lasso tool opens up a world of digital art possibilities. In this comprehensive guide, I‘ll walk you through everything you need to know to become a Lasso tool pro!
We‘ll cover:
- Locating the Lasso tool
- Creating a basic freehand selection
- Tips for drawing precise selection edges
- Adding to and subtracting from selections
- Working with your selection (applying effects, transforming, copying/pasting)
- Refining selection edges for a perfect cut-out
Whether you‘re a beginner looking to expand your Clip Studio Paint skills or a seasoned artist brushing up on fundamentals, by the end of this tutorial you‘ll have the knowledge to put the Lasso tool to use in your creative workflow. Let‘s get started!
Where to Find the Lasso Tool
The Lasso tool is located in the main toolbar on the left side of the Clip Studio Paint interface. Its icon looks like a lasso rope. If you don‘t see it immediately, it may be nested under the Selection tools sub-menu. Just click and hold the active selection tool to reveal the other options and choose the Lasso tool.

With the Lasso tool now active, you‘re ready to start making selections!
Making a Basic Selection
Creating a freehand selection with the Lasso tool is simple:
- Click on the part of your artwork you want to start the selection
- While holding down the mouse button, trace around the desired area
- Release the mouse button to complete the selection
The great thing about the Lasso tool is that you don‘t have to get the selection perfect on the first try. In the next section, we‘ll go over some ways to refine the selection, but first let‘s talk about some tips for getting a clean selection from the start.
Tips for Precise Selections
- Zoom in on the canvas so you can clearly see where you want the selection to go
- Take your time! There‘s no need to rush. Slowly and carefully trace the outline for best results.
- If you have a drawing tablet, using a pen instead of a mouse allows for more natural, precise movements
- To quickly undo your last selection, press Ctrl+Z (Win) / Cmd+Z (Mac)
With practice, you‘ll get a feel for how to guide the Lasso tool smoothly and accurately. But even pros use the following techniques to perfect their selections.
Refining Your Selection
Unless you have uncannily steady hands, chances are your freehand selection could use some fine-tuning. Fortunately, the Lasso tool makes it easy to adjust your selection by adding or removing areas.
Adding to a Selection
To add to an existing selection:
- Hold down the Shift key
- Draw a new selection around the area you want to include
- Release the mouse and the Shift key
The new area is now part of the active selection. You can repeat this process as many times as needed.

Subtracting from a Selection
To remove an area from your selection:
- Hold down the Alt key (Win) / Option key (Mac)
- Draw a selection around the area you want to subtract
- Release the mouse and the Alt/Option key
The intersecting area will be removed from the active selection. Again, repeat as needed.

By combining addition and subtraction, you can meticulously sculpt your selection to contain only the pixels you want. Once you have your selection just right, let‘s see what you can do with it!
Working with Selections
With an active selection, you‘ve isolated part of your artwork to work on without affecting the rest of the canvas. Here are a few fundamental things you can do:
Applying Effects
Maybe you want to brighten just one part of your drawing or change the color of a specific object. With your selection active, any filters, adjustments, or effects you apply will be constrained to the selected area.
For example, let‘s say I want to make the shirt on a character drawing more saturated. I‘d use the Lasso tool to select just the shirt, then apply a Hue/Saturation adjustment to boost the color intensity. The rest of the artwork remains unchanged.

Transforming
With the Lasso tool selection active, you can use the Edit > Transform menu to scale, rotate, skew, or distort the selected pixels. This is handy for making adjustments to composition, positioning, or perspective.
Copying and Pasting
A common use for the Lasso tool is to cut part of the artwork on one layer and paste it onto its own layer. Simply make your selection, hit Ctrl+X (Win) / Cmd+X (Mac) to cut, then Ctrl+V / Cmd+V to paste. The selection will appear on a new layer, allowing you to work on it independently from the original artwork.

Refining Selection Edges
For situations that call for a truly precise selection, Clip Studio Paint offers a few additional tools to fine-tune the edges of your Lasso tool selection. You‘ll find these options under the Select menu.
Expand Selection
The Expand Selection command allows you to grow your selection outward by a specified number of pixels. This is useful if you cut your original selection a bit too close and need to recapture some edge pixels.

Shrink Selection
The opposite of Expand Selection, Shrink Selection lets you contract your selection boundary inward by a pixel amount you specify. Use this when you want to pare down and tighten up your selection.

Blur Edges
The Blur Edges command applies a slight blur to the boundary of your selection, softening the hard edges. You can specify the level of blurring in pixels. This is helpful for blending your selection naturally with its surroundings, eliminating any stark cutoff.

Use these refining tools in combination with the addition and subtraction techniques covered earlier to dial in your selection to pixel perfection!
Putting the Lasso Tool to Work
We‘ve covered a lot of ground in this guide, taking you from Lasso tool basics to advanced selection and refinement techniques. Equipped with this knowledge, you‘re ready to incorporate this essential tool into your creative process.
The Lasso tool really shines in these scenarios:
- Selecting characters, objects, or other distinct elements to work on separately from the background
- Isolating parts of your artwork to apply localized edits, color adjustments, or effects
- Creating a custom shape selection to fill with color, patterns, or gradients
- Cutting out artwork to move to a different layer or document
- Selecting areas to protect when using other tools, like the eraser
Of course, this is just scratching the surface of what‘s possible! As you continue to use the Lasso tool in your projects, you‘ll undoubtedly find more creative and time-saving applications.
Level Up Your Selections
Learning to harness the power of the Lasso tool is a game-changer for any digital artist using Clip Studio Paint. It opens up so many new possibilities for editing artwork with precision and flexibility.
Remember to take your time when making your initial selection, and don‘t be afraid to zoom in close. Master the technique of adding to and subtracting from selections to get your desired area. And when you need an extra level of refinement, the Expand, Shrink and Blur Edges commands are there to help.
With practice, wielding the Lasso tool will become second nature, and you‘ll wonder how you ever got by without it! So dive in and start putting your new selection skills to the test. Your artwork will thank you.
