Before you start

Start with the largest official image you can find, ideally a PNG or SVG from a Sam's Club page or an official media kit. A small screenshot rescaled many times will hide the differences you are trying to compare. This task is local: download the image, inspect it in an image tool or browser, and compare versions side by side. You do not need an online logo analysis service.

Avoid relying on memory when checking dates or redesign announcements. If a source does not clearly state the year of a change, treat that date as unknown rather than guessing.

Step-by-step instructions

  • 1. Collect two or three logo versions that you can clearly identify: a current wordmark, an older wordmark if available, and any icon or badge used alongside the name.
  • 2. Put each version on a plain white or black background at the same display height. Do not stretch one version more than another; compare proportion and spacing, not thumbnail size.
  • 3. Check the wordmark first: the type treatment, letter spacing, and whether the apostrophe and capitalization are consistent.
  • 4. If the logo includes a separate mark, note whether it changed independently from the wordmark. Some brands update the symbol and the lettering at different times.
  • 5. Extract the main colors with an eyedropper or the Logo Lab Palette Extractor. Record the RGB or hex values instead of naming colors like "blue" or "navy," because similar shades look alike on different screens.
  • 6. Test color pairs that matter for the logo, such as the mark color against the background. Use a contrast checker if the logo will appear on a white web page or on signage.

Check the output

Zoom into the edges of each version at 200–400%. If the letterforms become blurred or the spacing disappears, the source image is too small for a fair comparison. Look for differences you can name: a change in letterform, a shift in color, an added outline, or a new arrangement of the mark and the name.

For file work, a PNG exported at the original pixel dimensions and a WebP converted at quality 80–90 should look nearly identical on screen. An SVG is useful only when it is a true vector file; a PNG saved with an SVG extension remains a raster image with the same scaling limits.

Common problems and next steps

A frequent problem is comparing a flat current image with an old scanned or photographed version. Lighting, paper texture, and camera angle can make the older logo look thicker or warmer than it was. Treat those variations as capture artifacts unless an official vector or clean digital file confirms them.

If you cannot find a clear date for an older version, base the comparison on visible details rather than naming a year. Changes in spacing, letter shape, or color are observable facts; release years are not. For redesign practice, isolate one change at a time: recolor first, then adjust spacing, then test a simplified mark. Keep the original file untouched and export each trial separately.
