Best free typefaces for UI design in 2026
My go-to sans serif free typefaces for optimal legibility and simplicity on your interface designs.
Website and app interfaces can quickly get cluttered. An easy way to declutter them is by simplifying the thing that takes up the most space, the text. Removing complexity helps to decrease cognitive load (the amount of brain power required to use an interface), improve legibility, and it looks a lot neater too. Over the years, I’ve tried and tested hundreds of typefaces and selected my top free typefaces for UI design.
What is a typeface?
A typeface is a set of related fonts with a similar style or aesthetic. Helvetica is an example of a san serif typeface. Fonts are variations within a typeface, like weights or sizes. For example, Helvetica Bold and Helvetica Regular are 2 different fonts within the Helvetica typeface.
There are 5 main classifications of typefaces: serif, sans serif, script, display, and monospaced. It’s safest to use a single sans serif typeface for most interface designs. To see why, let’s learn a bit about typefaces.
Serif typefaces
Serif typefaces include decorative tails or feet at the ends of letters (highlighted below). They’re suitable for use at large sizes for headings and often convey a traditional, classic, or formal mood. Serifs with wider letter spacing are more legible at small sizes, making them suitable to be used for body text.
Sans serif typefaces
Sans serif typefaces don’t include decorative tails or feet at the ends of letters. They generally look more modern due to their simplicity. Sans serif typefaces are highly legible, making them suitable for use at small sizes for body text and large sizes for headings. Due to their lack of character, sans serif typefaces are a neutral option that suits most interface designs.
Script typefaces
Script typefaces are based on handwriting. Their low legibility means that they’re not suitable for use at small sizes for body text. Script typefaces can be effective at conveying a formal or casual mood at large sizes in headings.
Display typefaces
Display typefaces come in a wide range of varied styles. They’re decorative typefaces specifically designed to be read at large sizes. Due to their strong character and detail, they can be especially good at conveying a range of different moods. Display typefaces aren’t suitable for use at small sizes due to their visual complexity.
Monospaced typefaces
In most typefaces, the horizontal space that a character takes up depends on its natural width. For example, an “i” takes up less space than a “w”. In a monospaced typeface, every character takes up the same amount of horizontal space. For this reason, they’re often used for displaying code. They’re also useful for displaying numbers to make them easier and faster to compare.
Tips to choose a typeface
With so many free typefaces to choose from, it can be difficult to know where to start. Here are a few tips to help you choose a suitable free typeface for UI design:
- Sans serif, as they’re generally the most legible, neutral, and simple. This makes them a safe option for UI design.
- Relatively tall lower case letters (x-height) and comfortable letter spacing for optimal legibility.
- ‘Variable’ fonts to allow for more style customisation using a single font file. Non-variable fonts have a limited set of weights and styles separated out into different font files. This takes up more space and can affect site performance.
- Modern geometric style for a contemporary vibe.
- Constant stroke thickness (low contrast) for a clean and minimal feel.
The typefaces on this list have most of these characteristics. A typeface for UI design doesn’t need to have all of these characteristics, but they generally help.
My top 3 free typefaces for UI design
Here are my go-to free typefaces for UI design. They’re all sans serif typefaces with a tall x-height geared for optimal legibility and simplicity.
1. Figtree
By Erik Kennedy
Figtree is one of my favourite all-round typefaces for modern UI design. Recently released, it’s like Erik combined all the nicest parts of the top typefaces. It’s very versatile too, as it has a simple and friendly vibe.
2. Satoshi
By Indian Type Foundry
You can’t go wrong with this modern and minimal sans serif. It’s neat, distraction-free, and comes with lots of OpenType features to allow for more customisation. Less curves make it feel a bit more sharp/serious.
3. DM Sans
By Jonny Pinhorn
Round letters with a nearly constant stroke thickness (low contrast) help make it neat and tidy. Tall lower case letters make it great for use in small text. It’s not a variable font, but I still love it anyway.
Other great free typefaces for UI design
With so many amazing free typefaces for UI design, it’s tough to limit it to just 3 typefaces. The following are some of my other favourite typefaces for interface design.
4. Plus Jakarta Sans
By Tokotype
Extra tall lower case letters (x-height) help make it legible and friendly. The almost constant stroke thickness (low contrast) helps to simplify this typeface and give it a minimal vibe.

5. Inter
By Rasmus Andersson
A favourite amongst designers. It’s great out of the box, but also comes with some really clever OpenType features under the hood. This allows you to tailor functionality and aesthetics to your specific needs.
6. Manrope
By Mikhail Sharanda
Manrope is a beautiful modern combination of different font types:
- Slightly condensed, so you can fit more text on a line.
- Tall rather than rounded (semi-geometric).
- Din/Grotesque Numbers are super clean too.
7. Open Sans
By Steve Matteson
A humanist san serif typeface that’s clean, modern, neutral, and friendly. It looks familiar as it was commissioned by Google in 2011. A relatively tall x-height makes it highly legible on screen at small sizes.
8. Urbanist
By Corey Hu
Modern and neutral, this geometric sans-serif will give your interface a clean and contemporary vibe. Its almost constant stroke thickness (low-contrast) and lack of curves makes it sharp and minimal.
9. Lato
By Łukasz Dziedzic
Lato is a very popular and clever typeface. It looks neutral at a small size, but shows its character at a large size. Curved corners add warmth and friendliness, while its condensed width helps reduce line wrapping.
10. Quicksand
By Andrew Paglinawan
Quicksand has a lot more personality than the other more neutral typefaces on the list. Its rounded ends make it soft and friendly, while its geometric shapes keep it modern and minimal.
I hope these simple sans serif typefaces come in handy for your next design project. They’re safe and neutral free typefaces for UI design, so they should work for most projects. I’m not saying that you shouldn’t use serif typefaces for interface design. They can work really well in lots of cases, but it’s generally safest to use simple sans serifs until you gain more experience.
