Ranking by blade gap size
The following, based on a measurement of blade gap and razor weight, will hopefully agree with most of the impressions of the shaving community. This list was compiled by multiple people; inaccuracies are bound to result, and therefore multiple listings for the same razor are possible and even desirable. If there is only one measurement of a given razor gap, it assumes very strict manufacturing tolerances and that the razor measured has not ever been dropped, etc. which we know to not be the case.
The easiest way to measure the blade gap is with a feeler gauge. How to do it is described here.
Table of blade gaps
- note, additional tables can be found on the discussion page for this article.
Blade gap, in 1/1000's of an inch [ +/- .001 inch ]
List order: Smallest gap size (mildest) to larger (more aggressive)
Clarification: blade gap, angle, weight, and blade exposure collectively influence the aggressiveness of a razor. Each individual factors may contribute relatively more or less for each person based on an his/her skin, hair, prep, choice of blades, or technique. Your Mileage May Vary (YMMV), and this chart should not be used as a general ranking of aggressiveness, mildness, or efficiency of the various razors. This page is only a (likely imperfect) listing/ranking of blade gaps.
If instead you are looking for a list of razors ranked by aggressiveness, please refer to our evolving project here:

Note: Gillette Adjustables
- Slim and Fat Boy range from .022 @ 1 to .045 @ 9; Fat Boy (195) weighs 79 gm, Slim Adjustable weighs 70
- the Black handle Adjustable ranges from .017 @ 1 to .041 @ 9 or 1 setting smaller than the Slim or Fat Boy
- Merkur Slant has a slightly variable blade gap, and is difficult to measure; it weighs 76 gm.
Note: Weber PH
- This gap was reported by 2 members independently from the June 2014 Weber production
Note: Rockwell 6S
- Rockwell 6S numbers have been taken from the Rockwell Razors site:
Subjective differences in ranking were limited to +/- .001 measurements (in inches)
so differences of .001 - .003 (.025 - .076mm) can be considered functional equivalent.
Some of the contributing measurements, as well as instructions for taking blade gap measurements can be seen at this page's source thread.
