What this style means
Presentation type must work at the audience’s viewing distance, not just on the editor’s laptop. Start with short statements, clear hierarchy and enough contrast before choosing a distinctive family.
The collection is a starting point for comparing letterforms. It does not promise that a font used for one project, brand or period is identical to any of these families.
Compare the families and their references
Open Sans, Source Sans 3 and Lato offer separate straightforward sans comparisons. Microsoft’s presentation guidance recommends familiar, simple sans forms and avoiding excessive all-capital or ornate text. These specific alternatives are our editorial choices.
Explore the full profiles for Open Sans, Source Sans 3, Lato. Each includes its own project description and source license, so you can judge the actual design rather than the category name alone.
Try it in a real layout
Test the longest heading and the most information-heavy slide in the actual presentation view. Microsoft suggests avoiding sizes below 18 points and using larger text when the audience is farther away; that is a starting point, not a guarantee for every room.
Use the same wording and approximate size in each specimen. The size and tracking controls help you inspect the design; the PNG is a visual reference rather than a complete page layout.
Downloads, copying and next steps
Open a family’s official font page from its specimen when you want the font files. The selected source distributions include open licenses; review the license included with the specific files you obtain, especially if you plan to modify or redistribute them.
Copying ordinary letters does not carry these typefaces to a different app. Use a font-aware design tool or export an image when the appearance matters. For the character-substitution alternative, read Unicode text versus real fonts.
Your questions, answered.
Is an 18-point font always large enough?
No. Viewing distance, display size, contrast and content affect readability. Use the real presentation environment to choose an appropriate size.
Are these live previews free to use?
Yes. You can edit and compare the specimens here without payment. Use each official source link to download the font and read the included license.
Why do copied words look different in another app?
The previews use actual fonts loaded on this page. Ordinary clipboard text carries the characters, not a requirement for another app to render the same font.
