What You Need to Start Drawing on a Computer
Drawing on a computer requires three things: software that lets you paint or sketch, a way to input your strokes (a mouse, trackpad, or stylus), and a display to see your work. You do not need expensive equipment to begin. A standard laptop with free or low-cost drawing software and a mouse will work, though a graphics tablet—a flat pad that connects to your computer and lets you draw with a pen-like stylus—makes the experience feel more natural if you have drawn on paper before.
The software you choose depends on what you want to draw and how much control you need. Some programs are built for painting and illustration, others for graphic design or photo editing, and some for both. Most offer a free version or trial period so you can test them before spending money.
Key Takeaways
- Free drawing software like Krita, GIMP, and Autodesk Sketchbook will let you start drawing when ready without buying anything.
- A mouse works for drawing, but a graphics tablet with a stylus gives you pressure sensitivity and feels more like drawing on paper.
- Layers let you draw separate parts of your image on top of each other without mixing them, which is one of the biggest advantages of digital drawing over paper.
- Brush settings—size, opacity, and hardness—control how your strokes look, and experimenting with them is how you learn what each tool does.
- Undo is unlimited on a computer, so mistakes cost nothing and you can try techniques without fear of ruining your work.
Choosing Software That Matches What You Want to Draw
Krita is free and designed specifically for painting and illustration. It has a full set of brushes, layer support, and a clean interface that does not overwhelm beginners. read it from krita.org and install it on Windows, Mac, or Linux. When you open it, you will see a blank canvas in the center, tool options on the left, and layers and other panels on the right.
GIMP (GNU Image Manipulation Program) is also free and works across all operating systems. It is more powerful than Krita for photo editing and detailed work, but the interface is busier and the learning curve is steeper. Use GIMP if you plan to edit photos or do precise graphic design work alongside drawing.
Autodesk Sketchbook is free for personal use and has a very straightforward, uncluttered workspace—just you and a canvas. It is excellent if you want to focus on drawing without learning many features. Procreate costs about $13 one time but only works on iPad, not Windows or Mac computers. Adobe Photoshop and Adobe Illustrator require a monthly subscription and are industry standard, but they are not necessary to learn drawing basics.
Start with Krita or Sketchbook if you are new to digital drawing. Both are free, fast to read, and will not frustrate you with hidden menus.
Setting Up Your Input Device
If you are using a mouse, you already have everything you need. Click and drag to draw a line. The software will record your movement and display it on screen. A mouse works, but drawing with one feels stiff because you cannot tilt it or press harder to change the line weight—the computer sees only whether you are moving or not.
A graphics tablet plugs into your computer via USB and sits on your desk like a mousepad. You draw on its surface with a stylus (a pen-shaped tool that comes with the tablet). The tablet sends your position, pressure, and tilt angle to the software, so pressing harder makes a thicker line and tilting the stylus changes the brush angle. Entry-level tablets from Wacom, Huion, or XP-Pen cost between $40 and $100 and work when ready after you plug them in and install the driver software from the manufacturer's website.
If you own an iPad, you can draw directly on the screen with an Apple Pencil, which gives you the most natural feel. If you use a Windows or Mac computer, a tablet is optional but worth the investment if you plan to draw regularly. For your first week, use whatever input device you have—mouse or tablet—and focus on learning the software.
Understanding Layers and Basic Tools
A layer is a transparent sheet stacked on top of other sheets. You can draw on one layer without affecting the others, erase from one layer without erasing from another, and rearrange them. This is the single biggest advantage of digital drawing over paper. In Krita, create a new layer by going to Layer > New Layer. You will see it appear in the Layers panel on the right side of the screen.
The Paintbrush tool is your main drawing tool. Select it from the toolbox on the left (it looks like a brush), then click and drag on the canvas to paint. The Eraser tool removes paint from the current layer without affecting layers below it. The Color Picker (eyedropper icon) lets you click on any color on your canvas to select it as your current color. The Selection tools let you select a region of your canvas and move, copy, or delete just that area.
Spend your first session opening the software, creating a new file (File > New), and drawing straightforward shapes—circles, lines, and squiggles—to get used to how your input device feels. Do not worry about making something finished. The goal is to feel the delay between your hand and the screen (usually less than a tenth of a second) and to see how brush size and pressure affect your strokes.
Adjusting Brush Settings to Control Your Strokes
Every brush has settings that change how it behaves. Size controls how wide the brush is—measured in pixels. A size of 5 makes a thin line; a size of 50 makes a thick one. Opacity controls how transparent the brush is. At 100% opacity, each stroke is fully solid. At 50% opacity, you can see through it to the layers below. Hardness controls whether the brush edge is sharp or soft. A hard brush (100% hardness) has a crisp edge; a soft brush (0% hardness) fades at the edges.
In Krita, these settings appear in the Tool Options panel on the left side after you select the Paintbrush. Adjust Size by typing a number or dragging the slider. Change Opacity the same way. Experiment: draw a line at 100% opacity, then draw another at 50% opacity, and see the difference. Draw with a hard brush, then switch to a soft brush and draw again. There is no wrong choice—you are learning what each setting does.
Pressure sensitivity is a setting that only works if you are using a graphics tablet or stylus. When enabled, pressing harder on the tablet makes the brush thicker or more opaque. Most tablets enable this by default. If your strokes do not change when you press harder, check the Pressure tab in Tool Options and make sure it is turned on.
Common Mistakes and How to Avoid Them
The most common mistake is drawing on the background layer instead of creating a new layer first. If you paint directly on the background, you cannot erase a single stroke without erasing everything behind it. Always create a new layer before you start drawing. It takes two seconds and saves you from frustration.
Another mistake is using a brush that is too small or too large for what you are trying to draw. If your brush is 3 pixels wide and you are trying to fill a large area, it will take forever. If your brush is 100 pixels wide and you are trying to draw fine detail, you cannot. Keep your brush size between 5 and 30 pixels for most work, and adjust it as you zoom in and out. Zoom in (scroll wheel up or View > Zoom > Zoom In) when you need to draw small details, and zoom out when you need to see the whole image.
A third mistake is not using Undo. If you make a stroke you do not like, press Ctrl+Z (Windows) or Command+Z (Mac) to undo it. You can undo dozens of times in a row. Many beginners try to "fix" a bad stroke instead of undoing it, which wastes time. Undo is free and unlimited—use it constantly.
Saving Your Work and Exporting for Sharing
When you finish drawing, save your file so you can edit it later. In Krita, go to File > Save As and choose a location on your computer. Krita saves in its own format (.kra file) which preserves all your layers. If you want to share your drawing on social media or email it to someone, you need to export it as a standard image file like .jpg or .png. Go to File > Export As, choose PNG (which keeps the background transparent if you want) or JPG (which flattens all layers into one), and click Export.
PNG files are larger but preserve quality and transparency. JPG files are smaller but lose some detail and do not support transparency. For sharing online, PNG is usually the better choice. For printing, ask your printer whether they prefer PNG or JPG—most accept both.
Frequently Asked Questions
Do I need a graphics tablet to draw on a computer?
No. A mouse works for drawing, though it feels less natural than a tablet or stylus. If you are just starting, use whatever input device you have. A tablet becomes worth buying after you have drawn for a few weeks and know you want to continue.
What is the difference between Krita and GIMP?
Krita is built for painting and illustration and has a simpler interface. GIMP is more powerful for photo editing and graphic design but has more menus and options. For drawing, Krita is the easier choice. Use GIMP if you also need to edit photos.
Can I draw on my laptop trackpad?
Yes, but it is awkward. A trackpad is designed for clicking and scrolling, not drawing. If you only have a trackpad, use it to learn the software, but consider buying an inexpensive graphics tablet once you are comfortable with the basics.
How do I fix a mistake I made five minutes ago?
Press Ctrl+Z (Windows) or Command+Z (Mac) repeatedly to undo strokes one at a time until you reach the point before the mistake. You can undo dozens of times. If you undo too far, press Ctrl+Y or Command+Y to redo.
What file format should I save in?
Save your working file in your software's native format (Krita uses .kra, GIMP uses .xcf) so you can edit layers later. When you are done and want to share, export as PNG for best quality or JPG for a smaller file size.
