What Does Font Size Mean – Definition, Measurement & What Pt Is

What Does Font Size Mean- Definition, Measurement & What Pt Is

Characters in a particular font have a size that is measured in pt (points) for printed documents. We refer to this size as font size. This means that a font size of 12 pt is equivalent to 1/6 of an inch in height. In web design, font size is measured in pixels (px). Other absolute values can be used to measure font size, such as mm, cm, and in, depending on the medium used.

The most legible font sizes for longer body text usually range between 8 and 12 pt, but the ideal size depends on the font used and other details. Captions, copyright information, and footnotes can be legible in 7 pt font, while 6 pt fonts often require good eyesight, such as legal disclaimers. It’s important to keep font size legible to ensure readers can easily read and understand the text.

Different Measuring Results

There are several things to consider regarding font size beyond just numerical measurement. Different fonts with the same body height can appear different in size and legibility, so it’s important to choose a font that is visually appealing and easy to read at the desired size.

Additionally, different devices and display settings can affect the appearance of font size and layout. For example, the recommended display setting on Windows is 150%, which can make fonts appear larger than they are.

Line height is also an important consideration when choosing font size. Smaller text typically requires more line height to ensure legibility. Overall, it’s important to consider font size, line length, and x-height to create visually appealing and easily readable typography.

Different techniques and tools are available for testing font size and layout, including bookmarklets and expert advice in the field. By taking the time to carefully consider font size and its impact on your design, you can ensure a visually appealing and effective final product.

Different Optical Appearance

Font size is a key aspect of typography that determines the size of characters on a page or screen. Web designers can change font size using pre-determined dimensions or units, including pixels, ems, and percentages. The CSS property font size allows designers to set the size of fonts on a webpage and update relative units.

Fonts can appear optically different even if they are measured similarly in size. Absolute-size keywords allow for easy font hierarchy but can limit accessibility. Designers create most fonts to be small, so that a screen can display more information at the same time. Understanding font size and its implications is essential for designers and anyone who works with typography.

Measuring Font Size

Measuring font size is a crucial aspect of creating readable content. The font-size CSS property determines the size of the font on a webpage. The font size plays a significant role in determining the space required between each line. The smaller the text, the more space it needs to become easily readable.

Choosing the correct font size for your website, social media, or print is essential. Other font-size-relative units, such as em and ex, are relative to the size set. Percentage values for font size are based on the parent element’s size. Resources available for better typography include guidelines on choosing a comfortable measure and colorizing text for line-length testing.

Hp Height

When measuring font size, you can use the hp height as one standard measurement, which measures from the upper edge of the “h” to the lower edge of the “p.” Typically, people measure font size in points (pt), with approximately 72 points in one inch. However, font size may vary across music engraving software due to different default staff sizes.

It’s important to note that cap height, which only measures the height of a capital letter without bowls, is not the same as the point size entered in applications. Measuring font size in cursive or handwritten fonts can also pose a challenge, as their sizes can vary greatly depending on the writer’s style.

The Cap Height

Measuring font size involves several factors, including the cap height, which is the height of a capital letter without bowls for a font. However, measuring cap height can be challenging. Capital and lowercase letter heights can vary between fonts but are generally consistent within a font family. Note that the font size measurement does not include the line gap in the body text.

Furthermore, cap height is purely a preference of the type designer and can be larger than the ascender and descender height. Additionally, the vertical bar character does not always equal the font’s em size and may not cover the whole height. Understanding these factors can help you choose the appropriate font size for your project and ensure that your text is legible and visually appealing.

Which Font Size For Which Purpose?

Which Font Size For Which Purpose

Font size is an essential aspect of typography and can impact the readability of texts on both screens and paper. The ideal font size for mobile screens is 16 pixels to avoid requiring zooming while ensuring the text is legible.

Em and rem units are scalable and have relative sizes, with em used for scaling and rem for root-based values to aid in responsiveness and reduce code redundancy. Pixel size, on the other hand, is an absolute unit of measurement and is not relative to anything. People commonly use small font size choices to fit more content on screens and reduce clutter.

While they may be appropriate in some instances, small font sizes can make reading difficult for some users, especially those with visual difficulties. Choose the font size carefully based on the purpose and context in order to ensure readability and accessibility.


Font size is a crucial part of typography, and it plays a significant role in determining the readability of text. In essence, font size refers to the height of a font, measured in points, from the bottom of the descender to the top of the ascender.

However, it can vary in how it appears optically, depending on the typeface. It is essential to choose the right font size for the purpose of your text, whether it’s for body copy, headings, or captions.

To ensure that your text is optimally readable and aesthetically appealing, it’s vital that you have an understanding of font sizes and how to measure them.
