When you're creating a business proposal, every detail matters. Your visuals need to be sharp, your formatting needs to be clean, and your structure needs to flow logically. You'll spend hours writing and rewriting sections to eliminate any confusion for your client.
On top of all that, you need to watch the length so you don't overwhelm them with information. With so many things to juggle, it's easy to overlook something that seems small but actually has a big impact - your font choice.
Why font choice matters in business proposals
The font you use directly affects how people perceive your content. You want a font that enhances readability, sets the right tone, and communicates your message clearly. Get it wrong, and you risk looking unprofessional and losing credibility.
Studies show that people unconsciously attribute personality traits to fonts. Your font tells clients what kind of business you run and affects how seriously they take you.
Serif fonts
Common associations: trust, traditionalism, reliability, respect
Examples: Times New Roman, Georgia, Garamond
Serif fonts have small "feet" at the ends of letters. They're commonly used in universities, law firms, and financial institutions, which creates an association with formality and authority. Perfect for traditional, professional industries.
Sans serif fonts

Common associations: modern, clean, approachable, welcoming
Examples: Arial, Helvetica, Calibri
Sans serif fonts don't have end strokes, making them sharp on screens. They feel more casual and approachable than serif fonts. Their straightforward design works well for everything from business reports to advertising.
Handwriting fonts
Common associations: elegant, creative, stylish
Examples: Brush Script, Nautica, Fertigo Script
These mimic human handwriting and add a personal touch. But use them sparingly - they can hurt readability. A header or two works fine, but avoid them in body text.
How to choose the right font for your proposals
Your font choice should match:
The nature of your business and proposal
Who your client is
Finance businesses benefit from serif fonts. Tech startups work better with sans serif. Whatever you choose, test for readability. If clients find your proposal tiring to read, they won't sign it.
