Brand typography audit: check your installed fonts

A brand guide may name the right typeface, but a design can still look different if the font is missing, the wrong weight is selected, or a character falls back to another font. Those mismatches can change line breaks, spacing, and the feel of a page.

Start by checking which fonts are available on the computer, then compare them with the brand rules and the files people actually use. The Installed Fonts tool lists fonts on your computer and lets you preview your own text in them.

Audit the fonts used in your brand

1. Open Installed Fonts in Chrome or Edge on a computer. Other browsers may show a reduced font list or none. Check your brand guide for the approved family names and required weights before you start.
2. Choose a sample that resembles your real content. Include a heading, body text, numerals, punctuation, and any accented or non-Latin characters your brand uses. For example, include names and prices if those appear in your materials.
3. Find each approved font family in the list and preview your sample. A font family is a group of related styles, such as regular, italic, and bold. Record which required family names appear to be available.
4. Check the styles you need, not just the family name. Note whether regular, medium, semibold, bold, and italic versions are available when your brand system calls for them. Do not assume that one installed style includes every weight.
5. Compare the preview with your reference design. Look at letter shapes, spacing, line breaks, numerals, and distinctive brand characters. Then open the actual project in its intended app or browser and check that it renders the same way there.

Keep a simple audit record with the approved family, required styles, whether each is installed, and any visible differences. Include the computer or browser checked, since another user's setup may have a different font collection.

What the results mean

The approved family and required styles are present

This computer has the named font files available to applications that can use installed fonts. It is a good starting point, but it does not confirm that every design file selects the right family and weight. Check a real document or page before signing off.

The family is present, but a weight is missing

The project may substitute a nearby style or create a synthetic bold or italic. Synthetic styles are generated from another font style and may not match the brand's intended design. Confirm whether the guide permits a substitute, or obtain the correct font file from your organization.

The family is not listed

The font may not be installed for this user, or the computer may have a differently named version. Check the exact family name in the brand files and confirm with the person responsible for font licensing before installing anything.

Some characters look different

The chosen font may not include every character in your sample. The operating system or application can display unsupported characters using a fallback font, which is another font used to fill a gap. Check the affected characters in the actual document, especially names, symbols, and accented text.

The tool preview looks right, but the design does not

The font list confirms availability, not which font an application has selected or how it handles embedded or web fonts. The project may specify another family, request a weight that is unavailable, or use a different font-loading rule. Inspect the project itself before changing the system font collection.

How to fix typography mismatches

1. Check the selected family and style. In the design app or website styles, compare the selected font family and weight with the brand guide. A file can use a fallback even when the approved font is installed.
2. Install the approved font if it is missing. Use a trusted, organization-approved font file and check its license first. On Windows 11, open Settings › Personalization › Fonts. On macOS, open Applications › Font Book to add and review fonts.
3. Use the correct weight instead of a visual substitute. If the guide calls for semibold, select the actual semibold style when available. Avoid replacing it with bold just because it looks close at one size.
4. Set a deliberate fallback for missing characters. If the font lacks a needed script or symbol, choose a compatible fallback and check the characters in context. On a website, review the font-family list and the font files and weights declared for the page.
5. Reopen and recheck the project. Some apps need to be restarted after fonts are installed. Check headings, body copy, buttons, and longer paragraphs, since a small change in letter width can alter wrapping throughout a layout.

What a browser font check cannot confirm

The Installed Fonts tool checks the font collection available to the browser on that computer. It does not prove that a website loads its intended web font, that a document embeds fonts correctly, or that a font license allows a particular use. A website may use font files hosted with the page rather than relying on the visitor's installed fonts.

For a design system audit, treat the font list as an availability check. Confirm the final typography in the actual application, browser, or exported file that your audience will see, and document any approved fallback before handing the work to someone else.
