Start with the reading situation
A typeface can look elegant in a specimen and still be tiring in an article, exhibition handout, or portfolio. Readability depends on how its letters behave at the size people will actually see, in the space available, and against the background you choose. Before adjusting any settings, decide what the text needs to do. A short caption invites a quick glance; a long essay asks readers to stay with it.
Test your design at its intended viewing size, not only while zoomed in on a computer. A poster may be seen from several steps away, while a phone page is held close but viewed in a narrow column. Print a sample if the final piece will be printed, or check a digital layout on a small screen if it will be read there. This simple change of perspective often reveals problems that are hard to spot while designing.
Choose a size that supports the text
For body copy, begin with a size that feels comfortable in context, then adjust rather than treating one number as universal. On a web page, 16 pixels can be a useful starting point for ordinary body text, but the best result depends on the typeface, screen, and layout. In print, point size alone is similarly incomplete: two faces set at the same size can appear noticeably different because their lowercase letters and proportions differ.
Set a sample paragraph in your chosen face and read it from beginning to end. If you lean closer, lose your place, or find yourself skipping words, try a slightly larger size before adding decorative emphasis. Give headings a clear size difference from body text, but avoid making every secondary element tiny. Captions, labels, and navigation still need to be read. A consistent hierarchy helps readers understand which words introduce an idea and which carry the detail.
Give lines enough room
Line spacing, sometimes called leading, is the distance from one line of text to the next. When it is too tight, the lines seem to merge and the eye has trouble finding the next one. When it is too loose, a paragraph can fall apart into separate stripes. For digital body text, a line height around 1.4 to 1.6 times the font size is a reasonable place to begin, not a rule to impose on every face.
Look at the spaces inside the letters and between the lines as one pattern. A typeface with a tall lowercase shape or generous internal space may need a different setting from a compact face. Also check paragraph spacing: a little separation can make blocks of text easier to scan without inserting blank lines after every sentence. If you change the type size or column width, review the spacing again. Settings that worked in a narrow layout may feel airy or cramped elsewhere.
Keep line length manageable
Line length affects the rhythm of reading. Very wide lines make the journey back to the start of the next line more demanding; very short lines interrupt phrases and create uneven edges. For sustained reading, a column that holds roughly 45 to 75 characters per line can serve as a starting range. There is no need to count every line. Look instead for a width that lets several words sit together without making a paragraph feel like a long horizontal sweep.
Column width and type size should be adjusted together. Enlarging text in a narrow column may create awkward line breaks, while shrinking it to fit a wide column can make the letters unnecessarily hard to see. On responsive pages, check both phone and desktop widths. In a printed leaflet or small art label, consider whether two narrower columns would help, but make sure the route from one column to the next is obvious.
Fine-tune spacing, then read it aloud
Letter spacing is usually best left close to a typeface’s default for ordinary paragraphs. Adding space between every lowercase letter can make words harder to recognize as groups. Short headings set in capitals may benefit from a little extra space, but check the result rather than applying a preset everywhere. Word spacing also deserves attention in fully justified text: if stretched gaps form distracting channels, try left-aligned text or revise the column width.
Finish with a reading test rather than a visual glance. Read a full paragraph aloud, notice where your eye hesitates, and ask someone else to try the layout without explaining it first. Check contrast, glare, and the difference between headings and body text alongside size and spacing. The goal is not to make typography invisible. It is to give the words a clear path so readers can pay attention to the ideas, images, and objects the text helps them explore.
