A stapler is one of the most-used tools in any office or classroom — yet many people never think carefully about which one to buy. Choose wrong and you’ll deal with jammed staples, bent pins, and frustrated colleagues. This guide covers everything you need to know to choose the right stapler and the correct staple size the first time.

The Three Main Stapler Categories

Mini Staplers (10–18 sheets)

Compact and lightweight, mini staplers are designed for personal desks, students, and anyone who needs a portable stapling solution. They use smaller staple sizes such as No. 10 and typically staple up to 18 sheets of 70 gsm paper. If you carry a bag to school or work every day, a mini stapler is worth keeping on hand.

Standard Office Staplers (25–50 sheets)

The workhorse of the office. Standard staplers use No. 3 (24/6), No. 35 (26/6), or the common 23/6 staple sizes and handle 25–50 sheets per stroke. Look for a model with an all-metal mechanism and a rear-loading staple compartment for the easiest refilling. This is the most suitable choice for the majority of office workers in Thailand.

Heavy-Duty Staplers (50–160 sheets)

Designed for high-volume stapling tasks such as financial reports, booklets, and legal documents. Heavy-duty staplers accept larger staple gauges from 23/6 up to 23/24, with some deep-throat models (long-reach staplers) allowing you to staple across the centre of A4 paper — ideal for creating booklets. These are essential for print shops, accounting departments, and schools that produce large batches of handout materials.

Staple Size Chart: Matching the Right Staple to the Right Stapler

The single most common stapler problem — jamming — is almost always caused by using the wrong staple size. Use this reference chart every time you purchase staples.

5 Tips to Extend the Life of Your Stapler

  1. Always use the correct staple size. Check your stapler’s label before buying a new box of staples.
  2. Never force it. If the paper is thicker than the stapler’s rated capacity, divide it into two stacks.
  3. Keep the staple compartment clean. Use a small brush to remove broken staple fragments monthly.
  4. Store in a dry location. Humidity causes staples to rust, which leads to jamming and tearing.
  5. Top up before empty. Running the staple strip all the way down stresses the feeding mechanism.
