Choose the brand font: how many types are enough?
The answer is not 'the more fonts, the more elegant', but rather the right role, the right number, tested on real materials.
For most brands, two typefaces are sufficient and optimal: one headline font with personality and one body font that is easy to read. Three typefaces are the maximum, and the third typeface should only appear when it has a clearly narrow function, such as technical numbers or sub-labels. More important than quantity is to test the fonts on real materials before locking the system.
Two typefaces are the sweet spot for most brands. Not because it’s a trendy number, but because two typefaces are just enough to create clear hierarchy and consistent management across all applications. More than three is risky, less than two limits personality. And before discussing quantity, there is a mandatory constraint for Vietnamese brands: the font must fully support Vietnamese diacritics.
Define roles first, choose fonts later.
Many brands choose fonts because they look good on a moodboard, then look for places to use them. Sinh Vũ does the opposite: listing all the roles that need to be covered first, then selecting fonts for each role.
Common roles in a brand system:
- Main title: large size, needs personality and strong weight.
- Body: read a large volume, prioritize readability over personality.
- Secondary labels and captions: small size, need to be sharp at reduced dimensions
- Numerals or technical codes: if the brand uses many price lists, data, or order codes.
Once the roles are clear, you will immediately see two lowercase letter groups covering the first three roles. Only when the fourth role appears should you consider a third letter group.
When to use one, two, or three typefaces
A typeface family with multiple weights: Suitable for minimalist brands that want absolute consistency or have a limited design budget and font licensing. The condition is that the typeface must have enough weights, at least Regular, Medium, and Bold, to create internal hierarchy.
Two typefaces: The default choice should be selected for most brands. One headline font with personality, and one body font that is easy to read. Enough to create hierarchy and personality while still being manageable.
Three typefaces: Only when the third typeface has a narrow and clear purpose, for example, a monospace font specifically for technical codes, or an accent font used very sparingly for special event titles. If you have not defined the purpose of the third typeface, it is a sign that it is not needed yet.
The principle of type pairing: contrast in harmony
Pairing two good typefaces is not just about choosing two beautiful fonts and placing them next to each other. The two fonts need to contrast enough for the reader to see a clear hierarchy while sharing some characteristics to avoid visual conflict.
The two terms must differ enough to clarify the hierarchy, but share some characteristics to avoid conflict.
Google Fonts Knowledge, Pairing Typefaces
Common characteristics to share often include similar x-height or comparable stroke weight. When these two factors differ too greatly, the letters placed next to each other may appear mismatched, even if each letter is beautiful on its own.
Regarding weight, Sinh Vũ maintains a maximum of three weights in a system: Regular for body text, Medium for subtitles, and Bold for main titles. Using more weights typically does not create additional hierarchy but rather adds confusion.
Common mistakes that cause fonts to break in real use
- Choose fonts on a mood board, not tested on real materials: Fonts that look beautiful at large sizes on design screens may lose detail at smaller sizes on business cards, or appear heavy in social media captions. Sinh Vũ always tests fonts on business cards, email headers, and at least one social media post before finalizing the system.
- Font lacking Vietnamese diacritics: This is the most common error with Vietnamese brands. When the font is missing characters, the system automatically inserts a fallback font for the missing parts, resulting in letters like ê, ơ, đ or tonal marks being replaced by completely different fonts in the middle of the brand text.
- Pairing two similar fonts: Two sans-serif fonts with the same proportions and weight next to each other can look like a technical error, not a style choice.
- Pairing two very different fonts: Two fonts with strong personalities, sharing the same title and body text, can conflict and lose visual direction.
- Do not check licensing for all channels: Some fonts have separate web and print licenses. Using print fonts on the web without the appropriate license poses real legal risks.
The viewpoint of Sinh Vũ
Sinh Vũ develops the typography system based on roles first: headings, body text, labels, codes. Each role has a specific font: no two fonts should compete for the same role, and no single font should carry too many roles of different natures.
the top priority is to fully support Vietnamese, as Vietnamese brands struggle most with diacritics. An elegant font that lacks diacritics on the letter "ế" is unusable, no matter how beautiful it looks on the inspiration board.
And the typeface must be tested directly on the client's actual application, not just in presentations. A beautiful mood board is not proof that the font works. A printed business card is the real evidence.

Frequently asked questions
Can free fonts on Google Fonts be used for branding?
Yes, but you need to check two things: the commercial license (most Google Fonts use the SIL Open Font License, allowing commercial use) and the level of Vietnamese support. Not all fonts on Google Fonts have a complete set of Vietnamese characters; you need to type a sentence containing the letters ê, ơ, ư, đ and the tonal marks before making a decision.
Do you need to use the same font across the website, print, and social media?
You should maintain the same font system for consistent identity, but check the licensing for each channel. Some fonts sell separate web and print licenses. Additionally, a font that looks good in large sizes on signage may not be sharp in small sizes in social media captions, so you need to test both ends of the font size.
What does 'contrasting yet harmonious' fonts mean, and what combinations are incorrect?
Contrast to clearly establish hierarchy: for example, a serif font and a sans-serif font, or a narrow bold font and a wide light font. Harmonize to avoid conflict: the two fonts should share some characteristics, such as similar x-heights or comparable weights. The most common mistake is choosing two fonts that are too similar, making them look like a technical error, or choosing two overly distinctive fonts that make the page look chaotic.
