Typography Rules
Understand the principle behind the finding. Browse topics, follow the exact plugin rule, or compare the language policy.
Choose the scale of the problem
Find a topic from its name, symptom or rule ID
No entries match. Try a shorter term or reset the filters.
Ordinary spaces and trailing whitespace
Recognize accidental separators without destroying intentionally structured text.
Non-breaking spaces and short-word connections
Keep intended semantic pairs together without turning whole paragraphs into unbreakable text.
Numbers and units
Protect a recognized value–unit relationship and preserve the original measurement.
Repeated words
Check meaning before deleting an apparent duplicate.
Quotation marks, apostrophes and nesting
Distinguish a quote form from its opening/closing role and regional convention.
Punctuation spacing and paired punctuation
Read the punctuation and locale before adding or removing a space.
Hyphens, en dashes and em dashes
Choose the mark by meaning, then apply the publication’s style.
Ellipsis and dot sequences
Separate omitted or trailing speech from literal sequences and leaders.
Repeated punctuation
Decide whether repetition is voice, notation or an editing artifact.
Hyphenation ladders
Review consecutive hyphenated line endings in the composed text.
Widows and orphans
Look at the paragraph and frame boundary before relying on a label.
Understand the topic →Short last lines
Judge the visual ending of the paragraph rather than a universal word-count rule.
Understand the topic →Rivers of white space
Check a supported corridor of whitespace across composed lines.
Understand the topic →Rag, texture and column balance
Compare reading rhythm and density with the intended page design.
Understand the topic →Leading, spacing and vertical rhythm
Understand the intended style baseline before normalizing local spacing.
Understand the topic →Overset and terminal-frame fit
Separate a text-fit problem from a decision about frame geometry.
Understand the topic →Manual breaks and empty paragraphs
Determine the structural purpose before deleting a character.
Manual indents and repeated tabs
Distinguish improvised alignment from deliberate text structure.
Date formats and ambiguous dates
Establish the factual date before changing its appearance.
Numeric grouping and decimal separators
Keep numeric value separate from its regional presentation.
Currency symbols, codes and spacing
Preserve the amount and identify the currency before normalizing typography.
Abbreviations and their following values
Review punctuation and spacing in the full phrase.
Capitalization and structural role
Compare headings and names by meaning and role, not only by their letter case.
Japanese and Korean line boundaries
Use supported boundary evidence with a competent language review.
