Choose the Right Shredder in 6 Steps

Work through each step in order — your answers narrow down the ideal model for your exact situation.

Step 4

What security level do you need?

Security levels are defined by the international DIN 66399 standard — P-1 (lowest) to P-7 (highest). The level you need depends on the sensitivity of your documents. See the full security level chart below for a detailed breakdown.

Step 5

Select paper feed capacity and bin size

A higher paper feed capacity means fewer passes to clear a stack. A larger bin means less frequent emptying. Both reduce interruptions during your working day.

📄
Sheet capacity — rated at 70–80 gsm standard paper. Heavier paper reduces effective capacity per pass. Match capacity to your typical stack size, not your maximum.
🗑️
Bin size — the larger the bin, the less often you empty it. Cross-cut and micro-cut waste is bulkier than strip-cut, so security-conscious users benefit most from larger bins.
⏱️
Duty cycle — personal shredders need rest after 5 minutes; heavy duty models run 30–60 minutes continuously. Match duty cycle to how long your shredding sessions typically last.
