What's the best format for PDFs?

For readability on screens, horizontal (landscape) formats are generally preferred when designing PDF presentations. In B2B sales, about 70% of sales decks are still viewed on PCs or laptops.

Choosing the Right Format

The key question is which format best optimizes space within an emlen Destination. There is no universal answer—it depends on the viewer’s screen size, aspect ratio, and browser settings (e.g., whether the bookmark bar is visible).

• 16:10 → Recommended for most cases. It offers the best balance, maximizes space, and ensures a clean, professional look across devices
• 4:3 → Displays at a page height zoom level
• 16:10 → Displays at a page width zoom level
• 16:9 → Also displays at a page width zoom level
