Bubble Letter S — How to Draw It + Free Printable Outline
Learn to draw a bubble letter S the easy way — and print a big, page-sized S outline to color, trace over, or cut out for a name sign. A bubble S is the curviest letter. Decorative bubble lettering for names, posters, cards and bullet journals — no account, no watermark.
How do you draw a bubble letter S?
Pencil a thin skeleton S first, then draw a fat rounded outline about a finger's width around every stroke and round all the corners — a bubble S is the curviest letter. Erase the pencil inside, ink the outline, and color it. Prefer to skip the drawing? Print the big bubble S outline below, or type any name into the free generator.
What a bubble letter S is for
Bubble letters are decorative, graffiti-style letters — normal letters puffed up fat and rounded like balloons, hollow inside so there's loads of room to color. People draw them for name art and door signs, birthday banners and posters, greeting cards, doodles and bullet-journal headers. The bubble S in particular turns up most often as the first big letter of a name — think STAR, SAM and SUPER.
This page is about the S STYLE and drawing it yourself. Every letter is bubbled a little differently because its skeleton is different: the S is the curviest letter — two opposite fat curves, the one most kids find trickiest. Below are the exact steps for the S, and a big page-sized S outline you can print to color, trace over with a marker, or cut out — no drawing skills needed if you'd rather start from the printable.
How to draw a bubble letter S, step by step
Four moves — the S is one flowing S-spine inflated into a fat curving ribbon.
-
1
1 · Pencil the S spine
Lightly draw a plain skinny S — a curve over the top going one way, then a curve under the bottom going the other. This single wiggly line is the spine your bubble ribbon wraps around.

2 · Inflate it into a fat curving ribbon
Draw a rounded outline a finger's width out on BOTH sides of the spine, following it all the way round — the S has no straight bits, so keep the whole outline smooth and flowing like a thick ribbon.

3 · Fatten the middle, taper the two tips
Let the ribbon bulge fattest through the middle turn and taper slightly at the two open ends, so it looks like a plump wave rather than a hose of even width.
Ways to use your bubble S
