A designer sets the word 'AVOCADO' with mathematically equal spacing between every letter. The result looks wrong — the 'AV' gap appears larger than the other spaces. What is the cause?
AThe font file is corrupted and the spacing data is incorrect
BThe angled strokes of A and V create a visual pocket of whitespace that appears larger than the spaces between straighter letter combinations
CEqual mathematical spacing is always visually correct; the designer is misperceiving the spacing
DThe letter V has a wider character box that forces extra space after it
Different letter shapes create different apparent whitespace even when technically equidistant. The diagonal strokes of A and V create an open triangular pocket between them that visually reads as more space than, say, the gap between two vertical strokes. Kerning compensates for this optical illusion by tightening specific pairs. Equal math does not produce equal optics — that is the foundational insight of kerning.
Question 2 Multiple Choice
A typographer needs to set a headline in all-uppercase letters and notices the letters feel cramped and dense. What adjustment is most appropriate?
AIncrease kerning on specific problem pairs like 'LT' and 'WA'
BIncrease letter spacing (tracking) uniformly across the entire headline
CSwitch to a different font with naturally wider letters
DReduce the font size until the density looks correct
Uppercase letters have more uniform heights than mixed-case text, which makes tighter spacing feel cramped and crowded. The solution is tracking — increasing uniform spacing across the whole word or line — not pair-specific kerning. This is a standard typographic rule: uppercase and small caps text typically benefits from added tracking to breathe properly.
Question 3 True / False
Mathematically equal spacing between letters will typically appear optically equal to a trained eye.
TTrue
FFalse
Answer: False
False — this is the central misconception kerning corrects. Different letter shapes create different amounts of apparent whitespace even when the measured gap is identical. Straight-sided letters (like H and I) feel closer than combinations with angled or overhanging strokes (like A and V, or T and o). Good typography requires optical equality, not mathematical equality.
Question 4 True / False
Kerning errors are most noticeable and most damaging at headline and display sizes rather than at body text sizes.
TTrue
FFalse
Answer: True
True. At body text sizes (10–14pt), small kerning imperfections are rarely noticed by readers — the text is read as a whole. But at display sizes used in headlines, logos, and posters, the enlarged whitespace between letters makes optical imbalances visible and signals a lack of craft. This is why professional typographers invest the most kerning effort in large-format text.
Question 5 Short Answer
What is the difference between kerning and letter spacing (tracking), and when would you use each?
Think about your answer, then reveal below.
Model answer: Kerning adjusts the space between specific letter pairs to achieve optical balance where individual letterform shapes create visual gaps. Tracking adjusts the overall spacing uniformly across an entire word, line, or block of text. Use kerning to fix pair-specific optical problems (AV, To); use tracking to adjust the overall density of a word or passage (e.g., adding tracking to uppercase headlines).
The two tools operate at different scales and solve different problems. Kerning is surgical — it targets the optical problem created by two specific adjacent shapes. Tracking is systemic — it shifts the overall rhythm of a typeset passage. A designer working on a logo might do both: add tracking to the whole word to open it up, then fine-tune specific problem pairs with kerning.
