Typography determines whether a website visitor reads your service description or closes the tab within seconds.
For bookkeepers building or refining a website, typography encompasses font selection, sizing, spacing, and contrast. When handled correctly, these elements guide visitors through your content and make it easier for them to understand your services and take action. When handled poorly, even well-written content becomes exhausting to read, and conversion opportunities disappear.
Font Selection That Supports Professional Credibility
Choose no more than two font families for your entire website: one for headings and one for body text. Sans-serif fonts like Arial, Helvetica, or Open Sans work reliably for body text because they render clearly across devices and screen sizes. Serif fonts can be effective for headings if they align with your brand, but using serif fonts for body text on screens often reduces readability, particularly on mobile devices.
Consider a bookkeeper who selected four different fonts across their homepage, services page, and contact form. The inconsistency created visual noise that distracted from the content itself. After consolidating to a single sans-serif font for body text and a bold sans-serif for headings, the site felt more cohesive, and the average time visitors spent on the services page increased. The shift occurred because visitors could focus on the information rather than processing constantly changing visual styles.
Avoid decorative or script fonts for any functional text. These fonts may appear elegant in isolation, but they become difficult to parse when used for paragraphs, navigation menus, or call-to-action buttons.
Line Length and Spacing for Sustained Reading
Body text should sit between 50 and 75 characters per line. Lines longer than this force readers to work harder to track from the end of one line to the beginning of the next, while shorter lines create a choppy, fragmented reading experience.
Line height, the vertical space between lines of text, should typically be set to 1.5 times the font size for body content. Headings can use tighter line height because they are shorter and designed to be visually distinct. Paragraph spacing should be larger than line spacing to signal a clear break between ideas.
These measurements directly affect how long visitors stay on your page. In our experience, bookkeepers who adjust line length and spacing as part of website upgrades for bookkeepers often see improved engagement without changing the actual content.
Font Size and Hierarchy Across Devices
Body text should never be smaller than 16 pixels on desktop or mobile. Text smaller than this becomes difficult to read without zooming, particularly for visitors over 40. Headings should follow a clear hierarchy: primary headings larger and bolder than subheadings, with consistent sizing throughout the site.
Mobile devices require additional attention. A font size that feels comfortable on a desktop monitor can appear cramped on a phone screen. Responsive design should scale font sizes proportionally, but the base size for mobile body text should still start at 16 pixels or higher.
Consider the way a visitor interacts with a services page. They scan headings first to determine whether the content is relevant, then read body text for detail. If your headings are only marginally larger than your body text, that scanning process becomes inefficient, and visitors may leave before understanding what you offer. Clear visual hierarchy allows visitors to navigate your content quickly and decide where to invest their attention.
Contrast and Colour Decisions That Improve Legibility
Text must have sufficient contrast against its background. Black text on a white background provides maximum contrast, but slightly softer combinations, such as dark grey on white, can reduce eye strain without sacrificing readability. Light grey text on white backgrounds, a common design trend, often fails accessibility standards and makes content difficult to read, particularly in bright environments or on lower-quality screens.
Coloured text should be used sparingly and only where it serves a functional purpose, such as highlighting a link or drawing attention to a call to action. Avoid using colour as the sole indicator of meaning, as this creates barriers for visitors with colour vision deficiencies.
The Web Content Accessibility Guidelines recommend a contrast ratio of at least 4.5:1 for body text and 3:1 for large text. Free tools such as the WebAIM Contrast Checker allow you to test colour combinations before committing to them. Ensuring strong contrast is not just about accessibility, it directly affects whether visitors can comfortably read your content and follow through to enquiry forms or contact details.
Alignment and White Space to Reduce Cognitive Load
Left-aligned text is easier to read than centred or justified text for most website content. Left alignment creates a consistent starting point for each line, allowing the eye to move smoothly down the page. Justified text, which stretches lines to align with both margins, often creates uneven spacing between words that disrupts reading flow.
White space, the empty areas around text and between sections, is not wasted space. It provides visual breathing room that helps visitors process information without feeling overwhelmed. Cramming too much content into a small area increases cognitive load and makes it harder for visitors to identify the most important information.
For bookkeepers, this is particularly relevant when presenting service descriptions, pricing structures, or client onboarding processes. Breaking content into clearly defined sections with adequate spacing makes complex information more approachable. This approach supports the broader goals of website development for bookkeepers, where the structure and presentation of content are as important as the content itself.
How Typography Affects Conversion and Enquiry Rates
Typography is not a decorative concern. It directly influences whether a visitor completes a desired action, such as filling out a contact form or calling your office. Poor typography creates friction by making content harder to read, which increases bounce rates and reduces the likelihood of conversion.
Websites with clear typography allow visitors to quickly understand what you offer, how you can help them, and what they should do next. When combined with a clear call to action strategy, these design decisions create a seamless path from initial interest to enquiry.
Typography also affects how search engines interpret your content. While search algorithms do not directly assess visual design, they do consider user engagement metrics such as time on page and bounce rate. If visitors leave quickly because your site is difficult to read, those signals can indirectly affect your rankings. Investing in typography as part of broader website content for bookkeepers ensures that your content is both discoverable and usable once visitors arrive.

Frequently Asked Questions
What font size should I use for body text on my bookkeeping website?
Body text should never be smaller than 16 pixels on desktop or mobile. Text smaller than this becomes difficult to read without zooming, particularly for visitors over 40, and can reduce engagement and conversion rates.
How many fonts should I use on my website?
Choose no more than two font families for your entire website: one for headings and one for body text. Using more fonts creates visual noise that distracts from your content and reduces professional credibility.
Why does line length matter for website readability?
Body text should sit between 50 and 75 characters per line. Lines longer than this force readers to work harder to move from one line to the next, while shorter lines create a choppy reading experience that reduces comprehension.
What is the best text alignment for website content?
Left-aligned text is easier to read than centred or justified text for most website content. Left alignment creates a consistent starting point for each line, allowing the eye to move smoothly down the page without disruption.
How does typography affect conversion rates?
Poor typography creates friction by making content harder to read, which increases bounce rates and reduces the likelihood of conversion. Clear typography allows visitors to quickly understand your services and what they should do next, creating a seamless path to enquiry.
