Understanding Kerning and Tracking in Image Editing
The character panel in image editing software is a dedicated typographic control center that allows designers to fine-tune the appearance, readability, and spacing of text. Among its most critical features are kerning and tracking, two distinct spacing controls that directly affect text density and visual appeal. This article explains how the character panel utilizes kerning and tracking to eliminate awkward gaps, balance character distribution, and elevate overall typography in graphic design projects.
The Role of the Character Panel
In programs like Adobe Photoshop, Illustrator, and other raster or vector editors, the character panel acts as the primary hub for manipulating text properties beyond basic font and size selection. It provides numeric fields and dropdown menus to manipulate horizontal character spacing with mathematical precision, ensuring text looks deliberately structured rather than haphazardly generated.
Managing Kerning in the Character Panel
Kerning refers to the adjustment of space between two individual, adjacent characters. Certain letter combinations—such as "AV", "To", or "WA"—often leave uneven negative space due to the diagonal or asymmetrical shapes of the letters.
Within the character panel, kerning is typically adjusted by placing the text cursor between two specific letters and entering a numeric value, or by choosing from automated options:
- Metrics (Auto) Kerning: Uses the font designer’s built-in spacing pairs.
- Optical Kerning: Uses the software's internal algorithms to adjust spacing based on the visual shape of adjacent glyphs, which is ideal when combining different fonts or using poorly spaced typefaces.
- Manual Kerning: Allows the designer to manually tighten or loosen the gap by incrementing values in points or units, ensuring perfect balance for large display text, headlines, and logos.
Controlling Tracking in the Character Panel
Unlike kerning, tracking adjusts the uniform spacing across an entire range of selected characters, a full word, a line, or a paragraph. The character panel allows users to highlight a block of text and assign a tracking value, expanding or condensing the space evenly between every letter.
Tracking is commonly used in image editing to:
- Improve Legibility: Adding positive tracking to small, all-caps text or thin fonts prevents characters from blending together on screen or in print.
- Fit Copy: Tightening tracking (negative values) helps fit long headlines into constrained design layouts without altering the font size.
- Create Stylistic Impact: High tracking values are widely used in modern, minimalist branding to give subheadings and taglines an airy, sophisticated look.
Practical Application and Best Practices
While both tools modify horizontal space, effective typography relies on using them in sequence via the character panel. Designers should first set the global tracking across the desired text block to establish the overall density and tone. Once the tracking is established, kerning should be applied manually to individual letter pairs—especially in large, prominent headings—to correct optical illusions and achieve a harmonious typographic rhythm.
