Best P4 ‘Micro-Cut’ Shredders (that are really Cross-Cut)

Micro-cut shredder or Cross-cut shredder?

Our Top Pick

How sensitive and secret is the information you want to shred? You are probably looking for a high security micro-cut shredder that destroys your documents into tiny and unreadable particles so you are protected against identity theft. Officially, according to DIN 66399, a micro-cut paper shredder falls under security level P-5 or higher (P-6 and P-7).

But when you browse for shredders online you will see that a lot of ‘micro-cut shredders’ are actually security level P-4, which really is a cross-cut type shredder. Fellowes, a well-known manufacturer of shredders, also states in a security level info-sheet that a micro-cut shredder has security level P-5 or higher.

Difference between security level 4 and 5

The difference between security level P-4 and P-5 is the official minimum size and shape of one paper particle after shredding a document. How small is a P-4 particle in comparison to a P-5 particle? According to DIN 66399 (source):

  • Security level P-4 particle size is equal or smaller than 0.248 in² (160 mm²)
  • Security level P-5 particle size is equal or smaller than 0.0465 in² (30 mm²)

There can be a 80% difference in particle size between a P-4 and P-5 paper shredder.

Below you can see a comparison of cross sectional shreds from a P-3, a P-4 and a P-5 shredder. You can tell that a P-5 paper particle is much smaller than a P-4 particle. But, it is important to note that a P-4 particle can be smaller than 0.248 in², the range of a P-4 shred sits between 0.248 in² and 0.0465 in². The smallest cross-cut shred can be actually called a micro/cross-cut shred. This means that the size of a P-4 cut can differ between paper shredder brands. That is because it is up to the manufacturer how small the shredder can shred your documents. Therefore it is important to thoroughly research the specifications of a paper shredder to find out the size of a paper particle.


  • Security level P-3: Destroys an A4 document into +-/ 200 pieces.
  • Security level P-4: Destroys an A4 document into +/- 400 pieces.
  • Security level P-5: Destroys an A4 document into +/- 2,000 pieces.

Is a P-4 paper shredder secure enough?

For destroying documents it is recommended to use a security level P-3 shredder or higher. Basically the minimum recommendation for shredding sensitive documents securely is to use a cross-cut shredder. But the term ‘secure’ is relative, it all depends on your own opinion and expectation how much security you prefer. Some people are satisfied with the size of paper particles from their P-3 shredder. However, others do prefer a smaller particle, that offers more security and protection, and therefore they opt for a P-4 (cross-cut) or even a P-5 (micro-cut) shredder.
