Headline Kerning: Fix the Awkward Pair Before Spacing the Whole Word

A cover title can contain the right words, the right typeface and one distracting gap. Two letters seem to pull apart while their neighbours sit comfortably together. The tempting fix is to tighten the entire title. That may close the conspicuous hole while squeezing several pairs that were already working.

For independent creators, this is a useful moment to separate a local spacing problem from an overall design choice. Before changing every gap, identify the pair that attracts your eye. A small, deliberate correction can be easier to judge than another round of adjustments to the whole headline.

Kerning and tracking solve different problems

Adobe’s kerning and tracking guide, updated on 2 June 2026, distinguishes the two controls. Kerning adjusts spacing between particular character pairs; tracking adjusts spacing across a selected range. A headline can therefore need a different overall feel and a correction to one pair. Those are separate decisions, even when both affect its width.

Consider a hypothetical title beginning with “AV”. In your chosen typeface, that pair might appear more open than the rest of the word. This is a sample to inspect, not a claim that every A beside every V needs tightening. The relevant evidence is the actual title in the actual font, weight and size you intend to publish.

Write the problem plainly before touching the controls: “The first pair appears disconnected; the rest looks balanced.” Compare that with “The whole title feels too widely spaced.” The first description suggests a local review. The second invites an overall spacing comparison. Keeping the descriptions separate makes it easier to tell whether an edit helped.

Start with the font’s spacing, then compare

Adobe describes Metrics kerning as using pair adjustments supplied in the font. InDesign’s Optical option instead considers the shapes of adjacent characters. Manual kerning permits an adjustment between a specific pair. These are documented InDesign behaviours; other design tools may expose different controls or use different terminology.

My practical recommendation is to keep a copy of the starting version and change one decision at a time. Compare the font’s existing spacing with an alternative automatic setting where your software supports one. If a particular pair still distracts, inspect that pair rather than assuming the entire word needs a tighter setting.

There is no useful universal number to prescribe for a creator’s unseen title. Ask what improves the word’s visual rhythm without making letters collide or creating another conspicuous gap. A setting borrowed from someone else’s thumbnail is not evidence that it suits your typeface.

Review the word, not only the gap

Imagine a designer preparing a fictional workshop poster called “AVENUE”. She notices the opening pair, reduces its gap and initially prefers the result. On looking again at the complete word, however, she finds that the beginning now feels compressed beside the middle. The next step is a comparison with the original, not a commitment to the first correction.

Make two or three labelled alternatives in the working file, with the wording, size and position held constant. Review them first as complete words, then as parts of the whole cover. Ask which version reads as a coherent title. Avoid making the gap the only thing visible on screen throughout the decision.

This exercise is an editorial production suggestion, not a claim that one spacing pattern guarantees better sales or engagement. The goal is to make a deliberate typographic choice and notice unintended changes. A title can be carefully spaced and still need clearer wording, stronger contrast or a different position in the composition.

Check the size your audience will see

A creator may design a large cover and distribute it as a small preview. Include that preview in the review. Compare the candidates at the intended display size, with surrounding artwork and any subtitle present. Use enlargement to investigate a problem, then return to the normal view before approving the result.

If the small version is difficult to read, reconsider more than spacing. Try a shorter title, a less delicate weight or a simpler arrangement as alternative designs. Treat these as options to assess in context, rather than rules that every thumbnail must follow. A local kerning correction should earn its place in the finished composition.

MaryChuks’s related guide, Optical Sizing: A Small Label Needs More Than a Smaller Headline, considers how a typeface’s design can vary for different text sizes. Optical sizing and optical kerning have similar names but different jobs. Keep that distinction clear when discussing changes with a designer or an AI assistant.

A web heading needs a browser check

For live web text, the W3C CSS Fonts Level 3 Recommendation, dated 20 September 2018, defines the font-kerning property. Its normal value enables kerning for proportionally spaced glyphs; none disables it; auto leaves its application to the browser. The property controls metric kerning using font data. It is not an instruction to reproduce InDesign’s Optical algorithm.

Ask whoever builds the page to review the real heading in the browser, including narrow layouts. Do not approve its spacing solely from a design mock-up. If a font or weight changes during handover, compare the resulting heading again before applying further adjustments. Establish what is being rendered before trying to correct its appearance.

Keep ordinary spaces for their linguistic purpose. I would avoid inserting extra spaces between letters as a makeshift way to position them. Request a typographic implementation that preserves the intended text, and include checking the copied heading among the handover tasks.

Give AI a bounded review brief

If you use AI to help review a layout, name the decision: “Inspect the headline for individual pairs that appear too open or too tight. Separate those observations from overall tracking. Do not rewrite the title. Identify the pair and explain what comparison would help.” Treat the response as a proposed review, then inspect the actual artwork yourself.

For final approval, retain the editable source and check the delivered export. Confirm the wording, intended font and spacing treatment, then view the title with its surrounding design. The useful result is a headline that works as a whole, with a record of intentional changes. One awkward pair deserves attention without automatically putting every other letter on trial.
