Typography and readability for long-form content

If your membership delivers long articles, lesson notes or detailed guides, your members spend most of their time on your site doing one thing: reading. How comfortable that reading is depends heavily on typography, the choice and arrangement of text on the page. Good typography goes unnoticed. Poor typography shows up as tired eyes, skimmed articles and a vague feeling that the content is harder work than it should be.

You do not need to become a designer to get this right. A handful of decisions about fonts, size, line length and spacing will make more difference than any amount of decoration, and once you have settled them, every piece you publish benefits.

Choose fonts for reading, not for personality

It is tempting to pick a distinctive font that expresses your brand. Save that for your logo and perhaps your headings. For body text, the words members read paragraph after paragraph, choose a font designed for comfortable reading on screens.

• Both serif fonts (with small strokes at the ends of letters) and sans-serif fonts (without them) can work well on modern screens. Pick one with clear, open letter shapes and a regular weight that is not too thin.
• Use no more than two font families: one for headings and one for body text. Many sites use a single family throughout, varying only the weight.
• Avoid script, handwritten or condensed fonts for anything longer than a heading.
• Check that the font includes true bold and italic versions, so emphasis looks deliberate rather than artificially stretched.

Test your choice with real content, not a single line of sample text. A font that looks elegant in a heading can become tiring over a long article.

Set a comfortable size and line length

Body text on many sites is simply too small. As a sensible starting point, set body text somewhere around 16 to 20 pixels on desktop, with 18 a common choice for reading-heavy sites, and no smaller than 16 on phones. Members can zoom, but they should not have to.

Line length, the number of characters in a line, matters just as much. When lines stretch across the full width of a wide monitor, the eye struggles to find the start of the next line. When they are very short, reading becomes choppy. A widely used rule of thumb is roughly 50 to 75 characters per line, including spaces. In practice, that usually means limiting the width of your main content column, even if the page itself is wider.

Give text room to breathe

Spacing is where many sites go wrong without realizing it. Three kinds of space matter:

1. Line height. The space between lines within a paragraph. Around 1.5 to 1.7 times the text size tends to suit long-form reading. Tighter spacing looks dense; much looser spacing makes paragraphs fall apart.
2. Paragraph spacing. A clear gap between paragraphs, roughly one line's worth, helps readers see where one idea ends and the next begins.
3. Space around headings. Put more space above a heading than below it, so the heading visibly belongs to the text that follows.

Align body text to the left. Fully justified text, stretched to both margins, creates uneven gaps between words on screens, particularly on narrow phone layouts, and can make lines harder to follow.

Make contrast work for tired eyes

Light gray text on white is a common design fashion and a common reading problem. Body text should be dark enough to read easily in poor light or on a dim phone screen. Very dark gray on white or off-white is comfortable for most readers. Check your colors against the contrast guidance in accessibility basics every site owner should know, which also covers heading structure for people using screen readers.

Links need to be recognizable without relying on color alone. Underlining links within body text is still the clearest convention.

Structure long pieces so members can scan

Even the most committed reader scans before they read. Typography supports scanning when the structure is clear:

• Break long articles with descriptive subheadings every few paragraphs.
• Keep paragraphs short on screen, often three or four sentences.
• Use bulleted lists for sets of items and numbered lists for steps.
• Use bold sparingly, for genuinely key terms rather than whole sentences.
• Set a key example or template apart in a quotation block.

Here is how a section from a hypothetical trade newsletter for craft brewers might change. The original is a single block of 180 words about renewing a production license, covering the deadline, the documents required and the mistakes that cause delays:

Before: one long paragraph, with the deadline mentioned in the middle of the fourth sentence and the list of documents buried in a string of commas.

After: a subheading, “Renewing your license without delays”; a two-sentence introduction; a bulleted list of the four documents needed; and a short paragraph on the most common mistake, with the deadline rule in bold.

The words are almost the same. The page is far easier to use, and a brewer checking the rule a second time can find it in seconds.

Check readability on every screen

Typography that works on your laptop can fail on a phone, where the same settings may give lines of only a few words or headings that wrap awkwardly. Look at your longest articles on a phone and a tablet as well as a desktop. The mobile checks in making your membership site work on every phone are a good companion to this.

Do not forget downloads. Worksheets and guides in PDF form often use tiny text to squeeze everything onto a page. If members read them on screen, a larger size and shorter lines help just as much there.

Your typography checklist

Open your longest, most important article and check it against this list:

• Body text is at least 16 pixels on phones and comfortable on desktop.
• Lines are roughly 50 to 75 characters long on a desktop screen.
• Line height is around 1.5 or more, with clear gaps between paragraphs.
• No more than two font families are in use.
• Body text is dark enough to read easily, and aligned left.
• Subheadings appear every few paragraphs and describe what follows.
• Links are underlined or otherwise clearly distinguished.

Fix these once in your theme settings, rather than article by article, and every future piece will be easier to read from the moment you publish it.
