Selling printable wall art on platforms like Etsy can be a lucrative venture, but the process of correctly sizing your digital files can be confusing. Sending files with incorrect dimensions or low resolution can lead to bad reviews and customer dissatisfaction due to pixelated or poorly scaled prints.
This guide breaks down the essential information you need to properly size your digital wall art, focusing on the five most common ratios and how to ensure high print quality using DPI.
📏 The Five Essential Print Ratios
To maximize the appeal and usability of your digital art, it’s recommended to offer your files in five common print ratios. These ratios cover the majority of standard frame sizes used by customers.
| Ratio | Common Dimensions (Inches) | Maximum Size to Create |
| 2:3 | 4×6, 6×9, 8×12, 10×15, 12×18, 16×24, 20×30 | 24 x 36 inches |
| 3:4 | 6×8, 9×12, 12×16, 15×20 | 18 x 24 inches |
| 4:5 | 8×10, 12×15 | 16 x 20 inches |
| ISO (International Paper Size) | A5, A4, A3, A2 | A1 (23.4 x 33.1 inches) |
| Special Size | 11×14 | 11 x 14 inches |
Focus on Maximum Size
A critical strategy for efficiency is to only create the largest file size for each ratio. A high-resolution image created at the maximum size (e.g., 24×36 inches for the 2:3 ratio) can be scaled down perfectly to all smaller sizes within that same ratio (e.g., 20×30, 16×24, etc.).
For example:
- Instead of creating separate files for 8×10, 12×15, and 16×20, you only need to create one file at 16 x 20 inches for the 4:5 ratio.
This means you will end up with five final digital files—one for the maximum size of each of the five core ratios.
📐 Understanding DPI and Pixel Calculation
To guarantee your printable art has a high print quality, you must understand and apply the correct DPI (Dots Per Inch) when creating your digital files.
What is DPI?
DPI (or PPI – Pixels Per Inch) is a measurement of print quality. It defines the number of dots (or pixels) of color information contained within one linear inch of the printed image.
- For high-quality, professional-grade prints, the standard requirement is 300 DPI.
Calculating Pixel Dimensions
To determine the required pixel dimensions for a high-quality (300 DPI) file, you simply multiply the physical inches of the print by 300.
$$\text{Pixel Dimension} = \text{Inch Dimension} \times 300 \text{ DPI}$$
Required Pixel Sizes for Maximum Prints
The table below shows the pixel dimensions you must use when creating your files to ensure they are high-resolution at 300 DPI:
| Ratio | Max Size (Inches) | Pixel Dimensions (at 300 DPI) |
| 2:3 | 24 x 36 | 7,200 x 10,800 pixels |
| 3:4 | 18 x 24 | 5,400 x 7,200 pixels |
| 4:5 | 16 x 20 | 4,800 x 6,000 pixels |
| 11×14 | 11 x 14 | 3,300 x 4,200 pixels |
| ISO (A1) | 23.4 x 33.1 | 7,020 x 9,930 pixels |
By creating your files at these large pixel dimensions, you ensure that customers can print them at any of the smaller sizes within that ratio without experiencing poor image quality or pixelation.
🛠️ Tools for Creating Wall Art Files
When preparing your art, especially if you are using AI-generated images (like those from Leonardo.ai or NightCafe), you may need to scale or vectorize the files to reach the required high pixel counts.
- Recommended Software: Photopea (free), Krita, or Affinity Designer.
- Software to Avoid (for sizing): Be cautious with platforms like Canva, as they may not provide sufficient control over DPI or the maximum pixel dimensions needed for these large, high-resolution files.
By adhering to these five ratios and the 300 DPI standard for maximum print sizes, you will provide your customers with high-quality files ready for printing at any scale, helping you build a successful and reputable Etsy shop.
