Based on the provided reference, the standard size for a Poster in Illustrator is 3300 x 5100 pixels, which corresponds to 11 x 17 inches at a resolution of 300 ppi.
Understanding Poster Size in Illustrator
When creating a new document in Adobe Illustrator, predefined sizes are often available for common print items like posters. These presets help users quickly set up their artboards with appropriate dimensions and resolution for print production.
Standard Poster Dimensions (from reference)
The reference specifies the following standard size for a poster:
- Pixels: 3300 px wide by 5100 px high
- Inches: 11 inches wide by 17 inches high
- Resolution: 300 pixels per inch (ppi)
This relationship between pixels, inches, and resolution is crucial for ensuring your artwork prints clearly. At 300 ppi, 11 inches multiplied by 300 equals 3300 pixels, and 17 inches multiplied by 300 equals 5100 pixels.
Here's how the reference details compare:
| Format | Pixel Dimensions (Width x Height) | Inches (Width x Height) | Resolution (ppi) |
|---|---|---|---|
| Letter | 2550 x 3300 px | 8.5 x 11 in | 300 ppi |
| Poster | 3300 x 5100 px | 11 x 17 in | 300 ppi |
| Postcard (US) | 480 x 672 px, 384 x 576 px | 5 x 7 in, 4 x 6 in | Not specified |
Practical Insights
- While 11x17 inches is a common poster size often referred to as "Ledger" or "Tabloid," poster sizes can vary widely depending on the intended use and printer capabilities.
- The resolution of 300 ppi is standard for high-quality printing, ensuring sharp details when the poster is viewed up close.
- Always confirm the required size and resolution with your print service provider before starting your design. They may have specific templates or size requirements.
In Illustrator, you can create a new document using these dimensions by going to File > New and entering the desired width, height, units (pixels or inches), and resolution (ppi).
