Choosing Dimensions That Match the Use
Decide the largest size the image will ever display at, then double it for high-density screens. A photo shown in an 800-pixel-wide column should be around 1600 pixels wide; anything beyond that is bytes nobody sees.
Keep the aspect ratio unless you have a specific reason not to. Changing width and height independently stretches faces and text in ways that read as unprofessional immediately, even to viewers who cannot say what is wrong.
Enlarging is fundamentally different from shrinking. Reducing discards information cleanly, while enlarging invents pixels that were never captured, producing softness or artificial-looking sharpening. Always resize down from the largest original you have.
Batch Consistency and Common Pitfalls
Product grids and galleries look noticeably better when every image shares exact dimensions. Mixed sizes cause subtle vertical misalignment that makes a page feel unfinished, and it is usually invisible until the whole grid is viewed at once.
Resize before compressing, not after. Compressing first bakes artefacts into the image, and then resizing resamples those artefacts into new ones.
Keep untouched originals in a separate folder. The moment a new placement needs a different crop or a larger version, the original is what saves you from reshooting or re-sourcing.
