Common Mistakes in Typography and Readability

Typography determines whether a prospect reads your services page or closes the tab within seconds.

A chartered accounting firm recently approached us after noticing their bounce rate sat at 68% despite strong referral traffic. The culprit was 14-pixel body text in a condensed sans-serif font paired with 1.2 line spacing. Visitors were leaving not because the content was poor, but because reading it required effort. After adjusting to 16-pixel text with 1.6 line spacing and switching to a more readable typeface, bounce rate dropped to 41% within three weeks. The content remained identical.

Why Font Size Below 16 Pixels Costs You Clients

Body text smaller than 16 pixels forces readers to lean forward and squint, creating immediate friction between your firm and a potential client. Most visitors access accounting websites on mobile devices where small text becomes nearly illegible without zooming. When someone needs to pinch and scroll horizontally to read your service descriptions, they will find another accountant whose website does not require that effort.

Consider a practice targeting small business owners in their 40s and 50s. This demographic often uses mobile devices during commutes or between meetings. If your font size sits at 13 or 14 pixels, you are excluding a significant portion of your target audience based purely on readability. The fix requires changing a single value in your stylesheet, yet many accounting websites still deploy text sized for desktop monitors from a decade ago.

Line Spacing That Encourages Reading vs Line Spacing That Repels It

Line height below 1.5 causes text to feel cramped and visually overwhelming. When lines sit too close together, the eye struggles to track from the end of one line to the beginning of the next, especially in paragraphs longer than three sentences. Accounting content often involves detailed explanations of services, fee structures, or compliance requirements. Dense line spacing turns these explanations into visual barriers.

A line height of 1.6 to 1.8 provides enough breathing room for comfortable reading without making paragraphs feel disconnected. For accounting firms publishing website content that explains complex tax strategies or corporate structures, generous line spacing helps clients absorb information without re-reading sentences. The difference between 1.3 and 1.7 line height might seem minor in isolation, but across a 600-word services page, it determines whether someone finishes reading or gives up halfway through.

The Typeface Choices That Signal Professional vs Amateur

Script fonts, decorative serifs, and overly stylised typefaces undermine credibility on accounting websites. A chartered accountant's website exists to communicate competence, accuracy, and trustworthiness. When the font looks better suited to a wedding invitation or a cafe menu, it creates cognitive dissonance. Clients expect visual simplicity that mirrors the precision they want in their financial advice.

Sans-serif fonts like Inter, Open Sans, or Roboto work well for body text on screens because they maintain clarity at various sizes and weights. Serif fonts like Georgia or Merriweather can work for headings or print materials but often feel dated or overly formal in body text on modern websites. The goal is not to be trendy but to be invisible. Good typography allows the reader to focus entirely on the message without noticing the typeface itself. If a visitor comments on your font choice, you have likely chosen the wrong font.

Contrast Ratios and the Clients You Lose Without Knowing

Light grey text on white backgrounds fails accessibility standards and excludes visitors with visual impairments or astigmatism. Many website development templates default to low-contrast colour schemes because they photograph well in demos. In practice, text with insufficient contrast forces users to highlight sections just to read comfortably, or they leave.

The Web Content Accessibility Guidelines recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. A simple test involves viewing your website in direct sunlight on a mobile device. If you cannot read your own services page outdoors, neither can your clients. High contrast does not mean stark black on white. A deep charcoal like #2C2C2C on an off-white background like #FAFAFA provides excellent readability while maintaining a refined appearance appropriate for professional services.

Paragraph Length and the Point Where Attention Drops

Paragraphs exceeding five sentences become walls of text that readers skip rather than engage with. Accounting websites often fall into the trap of trying to explain everything in a single paragraph because the writer wants to be thorough. Thoroughness means nothing if the explanation goes unread. Breaking content into shorter paragraphs creates natural pause points that help readers process information in manageable chunks.

Each paragraph should develop one idea completely before moving to the next. When discussing taxation services, for instance, one paragraph might cover individual tax returns while the next addresses corporate tax compliance. Mixing both in a single eight-sentence paragraph forces readers to mentally separate concepts that your formatting should have separated for them. This principle applies equally to website content about audit services, advisory work, or compliance offerings.

Heading Hierarchy That Guides vs Heading Hierarchy That Confuses

Inconsistent heading sizes or skipping heading levels disrupts the visual flow and makes it harder for readers to understand content structure. A proper hierarchy uses one H1 for the page title, H2 for main sections, and H3 for subsections within those main sections. When a website jumps from H2 directly to H4, or uses headings based on visual preference rather than structural logic, it confuses both readers and search engines trying to understand content organisation.

Headings also serve as scannable signposts for visitors who skim before committing to read in full. Chartered accountants often deal with clients who visit a website during brief windows between meetings or while comparing multiple firms. Clear, descriptive headings allow these time-pressed visitors to locate relevant sections quickly. Vague headings like "Our Approach" or "What We Offer" require reading the full section to understand its content, whereas "Tax Planning for Medical Professionals" or "Compliance Services for Manufacturers" communicate value immediately.

Column Width and the Fatigue Factor

Text that spans the full width of a large monitor becomes difficult to read because the eye must travel too far from the end of one line to the start of the next. The optimal line length for comfortable reading sits between 50 and 75 characters per line, roughly 10 to 12 words. When body text stretches across 150 characters because the layout uses no maximum width constraint, reading becomes a physical chore rather than a natural process.

Implementing a maximum content width of 700 to 800 pixels for text-heavy pages ensures readability regardless of screen size. This does not mean the entire page layout must be narrow. Backgrounds, images, and decorative elements can extend to full width while the text itself remains constrained to a readable column. Many accounting firms avoid this because they worry about empty space on large monitors, but empty space is not wasted space. It is the frame that makes your content readable and therefore valuable. Effective website management includes regular audits of readability factors like column width to ensure content remains accessible as design trends evolve.
