Document size guide
Presentation Size: 16:9, 4:3 and Slide Pixels
Presentation size is usually 16:9 widescreen for modern screens, with 4:3 still used for older rooms and templates. Check slide pixels, aspect ratio, and export workflow.

How we calculate this
Methodology and source handling
We convert physical sizes to inches, multiply by the selected DPI/PPI value, and round to whole pixels.
Quick answer
Copy-ready answer
Use 16:9 widescreen for most presentations. A 1920 x 1080 px export matches the 16:9 shape; use 4:3 only when the projector, template, or print workflow requires it.
Dimensions and specs
| Pixels | 1,920 x 1,080 px | |
|---|---|---|
| Inches | 13.333 x 7.5 in | |
| Millimeters | 338.7 x 190.5 mm | |
| Centimeters | 33.87 x 19.05 cm | |
| Aspect ratio | 16:9 | |
| Recommended DPI/PPI | 144 DPI/PPI for raster exports |
Pixels
Pixel dimensions by DPI
| DPI / PPI | Width | Height | Use |
|---|---|---|---|
| 150 DPI | 2000 px | 1125 px | Draft, large-format, or preview raster export. |
| 300 DPI | 4000 px | 2250 px | High-quality print or sharp raster handoff when required. |
Formula
How to calculate this size
338.66 mm x 144 PPI = 1,920 px wide.
Use this when the artwork stops at the finished edge.
Add 0 mm per side before calculating pixels when artwork reaches the edge.
Common mistakes
Avoid these document setup mistakes
Set the physical page or trim size first, then calculate pixels only for raster export or upload requirements.
Keep text, logos, page numbers, and important details away from printer, binder, or preview edges.
Use PDF, PPTX, or the required document format when text, links, vectors, and page size need to remain editable or searchable.

Workflow
Practical setup workflow
| Step | Check |
|---|---|
| Choose aspect ratio first | Switching between 16:9 and 4:3 after design can move and crop content. |
| Check the room | Use 16:9 for most modern screens; use 4:3 for legacy projectors or mandated templates. |
| Export for use case | Use PDF for handouts, PPTX for editable delivery, and PNG/JPG only for image slides or thumbnails. |

Checklist
Export checklist
| Item | Why it matters |
|---|---|
| PDF copy | Keeps type, vectors, and page size predictable for review or print. |
| Raster copy | Use the DPI calculator when a printer, marketplace, or upload tool asks for pixels. |
| Bleed and safe area | Add bleed only when artwork must run to the edge. |

FAQ
Common questions
What size should I use for presentation?
Use 16:9 widescreen for most presentations. A 1920 x 1080 px export matches the 16:9 shape; use 4:3 only when the projector, template, or print workflow requires it.
Do pixels matter for presentation?
Pixels matter only for raster exports. Start with the physical page size, then use DPI or PPI to calculate pixels for the required output.
What aspect ratio is presentation?
Presentation uses an aspect ratio of 16:9 for the primary size on this page.
