Photoroom uses design sizes that are measured in pixels. This is common to digital image software and as a general rule, the higher the number of pixels, the more detail the image contains (and the larger the file size).
It’s important to understand that pixel size refers to image detail, not physical size. A digital image doesn’t have a fixed physical size. How large it appears depends on the screen resolution (pixels per inch) or DPI for print media (dots per inch).
For example, let’s say you have a high-resolution image. If you display it on a phone and a 4K monitor, it will likely look good on both because it contains enough pixels to match the screen resolutions.
But if you display a low-resolution image instead, it might look fine on the phone (which has fewer pixels), but appear blurry or pixelated on the 4K monitor. That’s because the monitor has more pixels than the image, so the image has to be stretched to fill the screen, reducing sharpness and causing pixelation.
Low resolution image looks sharp on a small screen (left), but becomes blurry and pixelated on a larger screen (right).
Image sizes in Photoroom
The image size and resolution in Photoroom is defined by either:
The dimensions you choose when using the Resize tool
Photoroom has many pre-made sizes that you can choose from, each designed for common requirements such as social media sizes. You can also set your own custom sizes. For details, see Resize your designs in Photoroom.
The template you choose for your design.
When you import a photo, you can choose to apply a template. The templates in the Classics and Photo Editing Classics categories will automatically match the design size to the photo you have imported. Other templates use different sizes, depending on what they were designed for.
After selecting a template, you can manually resize your design if needed.
Choose an appropriate resolution
When resizing your images, consider how your design is going to be used.
For small-scale uses like profile pictures or online marketplace thumbnails, a smaller resolution is usually fine.
For larger uses such as banners, presentations, or print, use a higher resolution so the image maintains sharpness when scaled.
To choose a resolution, resize your image. For details, see Resize your designs in Photoroom.
