Compression measures how much force is required to deform a golf ball. The more force required, the higher the compression value. Consistency in compression value is important. A ball that compresses differently from shot to shot behaves differently from shot to shot. Ball Lab measures each ball individually and tracks the average and spread across the sample.
of 2026 Callaway Chrome Tour averaged 91, putting it in the strong range of the database. It has similar compression Srixon Z-Star Diamond AND TaylorMade TP5. Compression delta, which is the gap between the highest and lowest reading in the sample, came in at 7.7 points, a B+ grade and above average for the category. Several outliers in Box 2 account for most of that spread.
Ball Lab also measures compression symmetry which tracks how evenly the compression is distributed on each individual ball. of Tour in Chrome averaged 1.0 points of symmetry deviation, well below the field average of 1.9. The value suggests excellent stability under cover with no meaningful indication that the balls are softer or firmer on one side than the other.
The charts below detail the compression measurements on our sample.
