Listings show a few common sizes: small ‘confetti-sized’ pieces at about 15/64", strip pieces roughly 0.25" (1/4 inch), and one listing that notes 37 pieces at a 7/32" security level per pass. Actual shred size varies by model.

Some compact models have short duty cycles (run continuously about 2 minutes, then require roughly 15 minutes cool-down), while a high-capacity model in the listings is described as able to shred continuously without stopping.

Listed maximum speeds include about 6 pages per minute, 8 pages per minute, and up to 16 pages per minute for higher-capacity models.

Dimensions range from compact desktop units (about 12.25" H x 11" W x 5" D, ~3.2 lb) to mid-size home units (around 13.98" H x 13.39" W x 6.89" D, ~20 lb) and large commercial models (about 30.75" H x 17.13" W x 17.75" D, ~84.5 lb).

Listings frequently note the ability to shred credit cards, CDs/DVDs, staples, paper clips and junk mail in addition to paper.

Features include multi-level jam-prevention or jam-proof systems, electronic safety sensors that disable the feed when hands touch the paper opening, and manual-reverse or reverse controls to clear jams.

Many models offer auto start/stop or safe-start modes, reverse or manual-reverse controls to clear jams, overheat protection with LED indicators and required cool-downs, and pull-out wastebaskets for easy emptying.
