Common Mistakes to Avoid When Changing the Image Size

Resizing images is a common practice in business photography, but it's essential to do it carefully to achieve the desired results. Here are some common mistakes to avoid when resizing images:

  • Cutting off Important Content
  • Be mindful of what you're cropping out. Make sure you don't unintentionally cut off important elements or subjects in the image, such as people's heads or essential objects.

  • Overcropping
  • Avoid cropping an image too tightly. It's better to leave a little extra space around the subject to allow for adjustments and avoid a cramped or claustrophobic feel.

  • Ignoring Resolution
  • Cropping can affect an image's resolution. If you crop too much, the resulting image may not have enough detail for the purpose you have in mind, especially for print. Always consider the final output size and resolution.

Changing Image Sizes for Different Platforms


Resizing photos for different e-commerce sites is essential to ensure your product images display correctly. Each platform may have its own preferred image dimensions. Here's a general process for resizing photos for e-commerce sites.

Don’t forget to use a proper image editing app like Promeo, which has preset resized templates for top e-commerce sites so that you don’t need to find their guidelines by yourself. Online tools like MyEdit can also help with resizing your photos.
