7 Deadly font sins and how to avoid them

Are you guilty of the seven deadly font sins? We’re not the font police at Delilah, and we don’t insist that there are strict rules for font usage, whatever design purists might claim. Sometimes unexpected combinations can be delightful.

But, with so many fonts being created and released all the time, and with entrepreneurs using tools like Canva to create graphics for social media and blog use, we are seeing some issues around fonts cropping up again which should be avoided if you want to give your brand a super-professional look and build consistency. 

Too many handwritten fonts

We love that handwritten fonts are friendly, fun and approachable, but when it comes to handwritten, less is more. Limit yourself to a single handwritten font in your toolkit, and use it sparingly, as an accent. Think of handwritten fonts as being like the jewellery for a great outfit, not the outfit itself. When you’re choosing a handwritten font, ask yourself – is this right for my business? Or do I just like it? With handwritten fonts more than any other type, personal taste can come into play, so be careful to choose something that has the right image for your business. Unless you work in an education- or kid-related field, avoid childish handwritten fonts.

Too Trendy

We totally get the impulse to use trendy fonts – we’re the first to admit we love heading to Creative Market to check out what’s new, but just because it’s hipster, doesn’t mean it’s right for you. Running a brand-new corner café specializing in cold brew? The knock yourself out, but if your business isn’t trend-led, you may want to pass.

Comic Sans

Just no, not ever. And while we’re at it, we’re going to add Papyrus, Apple Chancery and Blackoak to our list of banned fonts.

Accent fonts for long amount of text

Some fonts are designed for large amounts of text, some aren’t. If you’re using a Display, Handwritten or Script font, be careful with how much you write using that font – they should be used for titles or accent words. There’s a reason why Arial, Times, Georgia, Verdana and Trebuchet are standard email fonts – they’re highly legible at small sizes and for big quantities of text.

Custom Fonts in Emails

Just because you CAN, doesn’t mean you should. Custom fonts cause all kinds of issues in email newsletters, so unless you’re using an accent font in an image, stick to the selection given by your email provider (and ask us for a recommendation if you’re not sure which to pick for your brand!).


We all know we shouldn’t write emails or SMS in CAPS, but when it comes to websites and social media, sometimes we forget that a little goes a long way. Don’t mix two all-caps fonts – just stick to one at a time.

Not the right font for your brand

When you’re searching for the right combination of fonts for your brand, it’s important to understand what fonts say about brands. As a general rule serif fonts (that means they have little curly ends on the letters) are more feminine, elegant and traditional, while sans serif fonts (literally – without serifs) are modern, clean and minimal.

If you’re feeling lost over font choices, we’d love to help – fonts are kind of our jam. Drop us a line at hello@delilahcreative.com and we’d love to chat about your business and the type of fonts you could consider using!
