How to Draw Block Letter I

Block letter I is one vertical stroke. That's it. In some block styles it gets short serifs (top and bottom horizontal caps) to distinguish it from the digit 1 and the lowercase L. The challenge with I isn't drawing it — it's spacing it. Because I has no horizontal bulk, it tends to look isolated next to wider letters and needs careful kerning.

How to Draw Uppercase Block “I”

Block I is a single vertical stroke from cap height to baseline. Optional short horizontal serifs may be added at the top and bottom to widen the silhouette.

How to Draw Lowercase Block “i”

Lowercase 'i' is a short vertical stroke at x-height with a dot (tittle) above the ascender line. Draw the stem from x-height to baseline, then place the dot directly above.

Practice Tips for Block Letter “I”

  • 1Decide whether your block I has top/bottom bars and stick to that choice everywhere.
  • 2Match its stroke width exactly to other capital stems — no thinner.
  • 3Test I inside a word at headline size to see how it interacts with wide neighbours.
  • 4When you have II adjacent, leave them slightly closer than HH to avoid a 'gap' that breaks the word.
  • 5If your context risks confusion with 1 or l, use the bars.

Frequently Asked Questions about Block Letter I

Should block I have top and bottom bars?
It depends on the style. Geometric sans (Futura, Avenir) keep I as a bare stem. Industrial and signage styles add bars to disambiguate from 1 and l.
How do I keep I from looking lost in a word?
Tighten the spacing on either side slightly. The standard side-bearings designed for wider letters leave too much white space around such a narrow form.
