How to Vary Line Weight in Procreate

2026-06-25

Flat, even lineart looks lifeless; varied line weight makes a drawing feel solid and three-dimensional. This guide explains where thick and thin lines belong, how to control weight with pressure or by hand, and how to taper line ends cleanly in Procreate.

Why line weight matters

Line weight is the variation in thickness across your lineart. Used well, it shows light, weight and depth before you add any color — it's one of the biggest upgrades you can make to a drawing. Even, uniform lines read as flat and amateur; varied lines read as intentional and dimensional.

The rules of where weight goes

A few reliable principles tell you where to thicken lines:

Outer contours thicker, interior detail thinner — the silhouette carries weight.
Shadow side thicker, light side thinner — implies a light source.
Where forms overlap or touch, thicker — these contact points anchor the drawing.
Closer/foreground objects thicker; distant ones thinner — creates depth.
Crevices and folds thicker — deep recesses read as darker.

Method 1: pressure control

With a pressure-sensitive ink brush, press harder for thicker lines, lighter for thin. Adjust the brush's pressure curve in Brush Studio → Apple Pencil → Pressure so the thick-to-thin range feels natural. Brush pens excel here — see how to ink with a brush pen.

Method 2: build weight manually

You don't need pressure at all. Ink with an even liner, then go back and thicken the contour, shadow side and contact points by drawing alongside the existing line and filling. This gives total control and is how many artists get perfectly deliberate weight. A technical liner from the inking category is ideal.

Method 3: taper your line ends

Lines look refined when they taper to a point rather than ending bluntly. Set taper in the brush's Stroke settings, or erase into the end of a line with the same brush to thin it out. Tapered ends where lines meet make joins look clean and natural.

Put it together

Ink the whole drawing at an even weight first.
Thicken the outer silhouette.
Add weight to shadow sides and overlaps.
Keep interior detail thin.
Taper the ends and tidy the joins.

This is part of the full inking workflow; for smoother lines first, see clean lineart.

Brushes and next steps

Any good free liner or brush pen handles line weight — grab one from the inking category or the best free inking brushes. Bold line weight is central to comic inking too.

Frequently Asked Questions

How do you vary line weight in Procreate?

Either press harder and lighter with a pressure-sensitive ink brush, or ink at an even weight and then manually thicken the lines that need it. Put weight on outer contours, shadow sides, and where forms overlap, and keep interior detail thin.

Where should lines be thicker in lineart?

Thicken the outer silhouette, the shadow side of forms, points where shapes overlap or touch, deep folds and crevices, and closer foreground objects. Keep interior detail and the light side thinner. This implies light, weight and depth before any color.

How do I make my line ends taper in Procreate?

Set the taper amount in the brush's Stroke settings so strokes thin to a point automatically, or erase into the end of a line with the same brush to taper it by hand. Tapered ends make line joins look clean and professional.

Do I need a pressure-sensitive brush to vary line weight?

No. Pressure makes it intuitive, but you can build weight entirely by hand: ink with an even liner, then thicken the contours, shadow sides and contact points afterward. Manual weighting gives you complete, deliberate control.
