Listings show two common punch diameters: about 1/4 inch and a larger 9/32 inch. The exact size depends on the specific tool.
The sheets are standard paper. Manual hole punches are described as metal tools, often finished with rubber or soft plastic grips; one model lists a TPR (thermoplastic rubber) handle.
Available rulings include wide-ruled, college-ruled, and quad/graph. The loose-leaf filler sheets are listed at a 20-pound paper weight.
Adjustability varies by model. Some desktop 3-hole punches have fully adjustable punch heads that let you configure for 2 or 3 holes; the listings note a 9/32" hole size for those tools.
Many filler sheets—and some composition-style notebooks—are supplied with three pre-punched holes for standard ring binders.
Common sizes shown in the listings are roughly 10.5 × 8 inches for many filler (loose-leaf) sheets and about 8.5 × 11 inches for composition-style or standard sheets. Exact sizes can vary by product.
Some filler and graph sheets are described as having reinforced punch holes or reinforced edges, which are noted to resist tearing and reduce ripping.
Many punches include built-in waste holders or confetti catchers; some listings mention a high-capacity tray that holds more punch-outs for longer use.
