How to draw with a mouse vs a finger (and a stylus)

At a glance

Drawing with a mouse

A mouse is a precise pointing device that is terrible at curves, because your hand naturally rotates around the wrist. Change how you hold it and it becomes surprisingly capable.

• Lock your wrist. For any stroke longer than a few centimetres, move your whole forearm from the elbow. Wrist movements produce arcs; arm movements produce controlled lines.
• Draw fast. Slow mouse strokes pick up every tremor. A quick, decisive stroke is smoother — and with unlimited undo, a wrong one costs nothing.
• Break curves into short strokes. Build a circle from four or five overlapping arcs rather than one loop.
• Rotate the subject, not your hand. Some directions are easier than others (most people find pulling down-and-left easiest). Plan strokes in your strong direction.
• Lower the sensitivity in your system settings while drawing. Fewer pixels per centimetre of movement means more control.

The mouse’s great strength is the straight line and the exact placement. It’s ideal for the drawing board: diagrams, plans and boxes-and-arrows.

Drawing with a trackpad

Trackpads are the hardest input to draw with, because clicking and moving at the same time is awkward. Two tricks help:

• Two hands. Hold the click down with your other hand’s thumb and draw with one finger of your drawing hand.
• Tap-to-drag. Many laptops have a “drag lock” or “three-finger drag” setting (on a Mac it’s in Accessibility → Pointer Control). Turned on, you can draw with one finger without clicking.

Keep trackpad drawings loose: doodles, cartoons, the five-minute ideas. Fighting for precision on a trackpad is frustrating.

Drawing with your finger

A fingertip on a phone or tablet is the most natural input there is — you’ve been drawing with your fingers since before you could hold a crayon. Its weakness is that your finger hides what you’re drawing and is wide, so fine detail is hard.

• Draw big. Fill the canvas. Detail drawn large and viewed small looks crisp.
• Use bigger brush sizes. Finger drawing suits painting, colouring and bold outlines.
• Turn the device to landscape for more room and a more comfortable arm angle.
• Use the side of your fingertip rather than the pad, to see more of the line.
• Keep your hand off the screen. In a browser, a second touch can be read as a new stroke — the free studio ignores extra fingers while you draw, but the app’s full-screen canvas handles palm contact better.

Most kids draw this way, which is why the kids’ canvas uses chunky crayons and a big brush by default.

Drawing with a stylus

A stylus — Apple Pencil, a Samsung S Pen, a Surface pen or a drawing tablet — is the closest thing to paper. Pressure-sensitive pens make lines thicker as you press harder; the free studio reads pressure where the browser provides it.

• Draw from the shoulder for long lines, just as you would on paper.
• Rest your palm on the screen if your device supports palm rejection — it steadies your hand.
• Hold it further back for loose sketching, closer to the tip for detail.

Cheap rubber-tipped styluses are basically a finger, without pressure. They’re fine for kids and for reducing smudges, but they won’t give you the precision of an active pen.

Which should you use?

The one you have. Every input can make good drawings — the techniques above matter more than the hardware. If you have a choice:

• Diagrams and precise shapes: mouse.
• Painting and colouring: finger on a tablet.
• Sketching and line art: stylus — or a mouse with the elbow technique.

Whatever you use, warm up for two minutes first: fill a sketchpad with straight lines and circles drawn as fast as you can. Your hand needs a minute to calibrate to the input.
