As a design element, font size is primarily responsible for how legible your text is. But it also plays a subtle but powerful role in dictating the overall tone and feel of your design. In this post, we’ll take a closer look at what font size is, how it works, and how you can use it to create better designs.

What is font size?

Font size is the measure of a typeface in terms of the height of its characters. In digital typography, font sizes are usually measured in pixels or points. On the web, font size is usually defined in terms of pixels, and browsers will do their best to render text at the requested size. In print design, on the other hand, font sizes are traditionally measured in points — 1 point is equal to 1/72th of an inch.


The size of a font is usually measured in points. The difference between two point sizes is usually equal to 1/72 of an inch. The larger the point size, the larger the font will appear. The smaller the point size, the smaller the font will appear.

How font size affects your design

When it comes to font size, legibility is key. You want your readers to be able to easily read your content, without straining their eyes. At the same time, you don’t want your fonts to be too big or bulky, as this can make your design look juvenile or unprofessional. So how do you strike the perfect balance?

There are a few things to keep in mind when it comes to font size and legibility. First of all, the larger the font size, the more legible it will be. This is because big fonts are easier to read than small fonts. Secondly, Sans Serif fonts (such as Arial or Helvetica) are generally more legible than Serif fonts (such as Times New Roman or Georgia). This is because Sans Serif fonts have a clean and simple design, which makes them easy to read.

Finally, it’s important to consider the spacing of your words and letters. If your text is too cramped together, it will be difficult to read. Conversely, if your text is too spread out, it will look disorganized and messy. The best way to achieve good spacing is to use a combination of font sizes and line heights. For body text, a good rule of thumb is to use a font size that is big enough to be legible, but not so big that it looks out of place. For headings and titles, you can use a larger font size for emphasis. And for line height, you want to aim for around 1.5-2 times the height of your font size.

What is font size and how does it affect your design? Font size is a measurement of the average height of the letters in a given typeface. The generally accepted range for body text is 12-14pt. Larger sizes are typically used for headlines, while smaller sizes are used for footnotes and captions. The choice of font size has a direct impact on the readability of your text, and therefore, on the overall success of your design.

Text that is too small is difficult to read and will cause eye strain. On the other hand, text that is too large can appear overwhelming and may actually make it more difficult to process information. The right font size will strike a balance between these two extremes, making your text easy to read while still allowing for a variety of other design elements to take center stage.

When choosing a font size, it is important to consider the different ways that your text will be used. For instance, body text should be larger than headings or captions, which allows readers to quickly scan a document and find the information they are looking for. Likewise, you may want to use a larger font size for headlines or call-to-action buttons in order to grab attention and make them stand out from the rest of your design.

In general, designers should aim for a balance between legibility and impact when choosing font sizes for their projects. By taking the time to select an appropriate font size, you can ensure that your text will be easy to read while still making an impactful statement.


One of the most important aspects of typography is accessibility. Body text should be large enough to be read easily by the majority of your audience. Keep in mind that some viewers may have impaired vision, so it’s important to choose a font size that will be legible for everyone.

In general, larger font sizes are better for accessibility. However, there are some circumstances where smaller font sizes may be appropriate. For example, if you have a lot of content on one page, you may need to use a smaller font size to keep everything within the viewer’s field of vision.

It’s also important to consider the overall design when choosing a font size. For example, if you want to create a feeling of sophistication, you might choose a smaller body text size so that your visitors will perceive your site as being more upscale. On the other hand, if you want to create a feeling of fun and excitement, you might choose a larger body text size so that your visitors will perceive your site as being more lively.

The bottom line is that there is no “right” font size for all situations. The best way to choose a font size is to experiment with different sizes and see what looks best for your particular design.

Emotional Response

Your font choice will create an emotional response in your reader that can be positive or negative. The wrong font can make your website look unprofessional or even hostile. Conversely, the right font choice can convey trustworthiness and approachability.

Size is one of the most important aspects of choosing a font for your website. The size you choose will affect readability and how users interact with your site. It’s important to find a balance between a size that is too small to read and one that is so large it feels overwhelming.

The overall tone of your website should be taken into account when choosing a font size. A site that is meant to be fun and playful can have a larger font than a site that is meant to be serious and professional.

Your chosen font should also be readable on all devices, including mobile phones and tablets. This means that you need to choose a sans-serif font, as serif fonts are generally more difficult to read on screens.


So, what have we learned? Font size is an important factor in design and can have a significant effect on the readability and overall look of your project. Be sure to consider all the different aspects of font size before making your final decision. And, as always, experiment with different options to find what works best for you.
