In B2B procurement, healthcare, wealth advisory, property, and consumer services in Singapore, many of the buyers holding the largest budgets—company founders, senior directors, medical specialists, and multigenerational families—are over 45. Yet young web designers frequently build websites on 27-inch studio monitors using 13px light-grey text on white backgrounds, or unstyled white text over pale table cells that become completely invisible.
Improving website readability and accessibility is not just a compliance exercise—it directly lifts conversion rates. Alongside our mobile UX friction checks, run these seven readability and accessibility checks across your website.
1. Enforce WCAG AA+ contrast ratios (especially inside dark-mode themes & tables)
Why it matters: Dark-mode websites look sleek when engineered properly, but break immediately when a blog post or plugin injects a light background container (#f8fafc) without overriding the theme’s default white body text—rendering the text invisible.
The standard: Maintain at least a 4.5:1 contrast ratio for normal body copy (and 7:1+ for tables and technical checklists), using explicit dark-slate table backgrounds (#111921) with crisp off-white text (#f1f5f9) on dark themes.
2. Keep body copy at 16px–18px with 1.6–1.75 line height and 65–75ch line width
Why it matters: Tiny 13px font sizes force readers to squint on mobile screens, while stretching a paragraph across the full 1440px width of a desktop monitor makes the human eye lose its place when jumping from the end of one line to the start of the next.
The standard: Set base paragraph text to 16px–18px, line-height to 1.65, and constrain article reading columns to 680px–780px (65–75 characters per line).
3. Scale H1 and H2 headings proportionally with clamp() (no giant 65px walls)
Why it matters: When a WordPress theme sets single-post H1 titles to a fixed 65px and H2 subheadings to 48px, a 12-word listicle title wraps onto six giant lines that push the entire article off the screen.
The standard: Use fluid responsive typography—such as clamp(1.85rem, 3.2vw, 2.5rem) for article H1 titles and clamp(1.35rem, 2.2vw, 1.65rem) for H2 section headings—with a tight 1.25–1.35 line-height.
4. Never rely on colour alone to indicate form errors or stock status
Why it matters: Roughly 8% of men have red-green colour vision deficiency. Highlighting an invalid form input solely by turning a 1px border from grey to red—with no error icon or text message—leaves users wondering why the form will not submit.
The standard: Pair every form validation state and stock indicator with an explicit text label and icon (e.g., “⚠ Please enter an 8-digit Singapore mobile number”), aligning with our form UX checklist.
5. Visible <label> tags above every form input (not disappearing placeholders)
Why it matters: Using light-grey placeholder text inside an input box instead of a permanent label above the box means that as soon as a user starts typing—or when browser autofill populates 6 fields at once—they can no longer verify which field is which.
The standard: Place a permanent, high-contrast <label> directly above every input field and link it via the HTML for attribute.
6. Descriptive link anchor text (eliminate vague “Click Here” or “Read More” links)
Why it matters: Both screen-reader users navigating by links and search engines evaluating internal link authority rely on the anchor text itself to understand where the link goes.
The standard: Make the linked words describe the destination explicitly (e.g., compare our monthly social media subscription plans rather than “click here”).
7. Keyboard navigation (Tab order), focus rings and pauseable motion
Why it matters: Power users, executives on laptops, and assistive-technology users frequently navigate forms and menus using the Tab, Enter, and Escape keys. Stripping outline: none without a visible :focus-visible ring makes keyboard navigation impossible.
The standard: Maintain a clear brass or teal :focus-visible outline on all interactive buttons, links, and form fields, and honour prefers-reduced-motion for users sensitive to parallax animations.
Website Readability & Accessibility QA Rubric
Audit your core templates against these seven typography and UX standards:
| Readability Element | Broken / High-Friction Pattern | Accessible High-Converting Standard | Impact on Buyer Experience |
|---|---|---|---|
Heading Scale (H1/H2) |
Fixed 65px H1 / 48px H2 overflowing mobile screens | Fluid clamp() sizing with 1.25–1.35 line height |
Clean hierarchy without overwhelming the viewport |
| Dark-Theme Table Contrast | White text inherited on light #f8fafc cells |
Dark #111921 / #16212b cells with #f1f5f9 text |
100% legibility across dark & light browsers |
| Body Copy Measure | 13px grey text stretched across 1400px width | 16–18px high-contrast text in 680–760px column | Effortless reading for executives of all ages |
| Form Inputs & Errors | Placeholder-only fields & colour-only red borders | Permanent top <label> + explicit text error message |
Higher form completion & zero autofill confusion |
