Grading for bouldering
This table shows that bouldering utilises a variety of grading systems, although two, V grades and the Font system are the most widespread.
||Peak Bouldering Grade
||Font Bouldering Grade
||Sport Grade (traverses)
The B system
(as used in the Peak Bouldering Guide) is essentially the same as the V system
, although occasionally traverses are given French sport climbing grades
. It should also be noted that the Northumberland Bouldering Guide uses a system unique to that county, although it appears similar to both V and B grades.
The UK technical grade operates within all of the other systems, as it indicates the difficulty of the hardest single move
Meanwhile the UK technical grade operates within all of the other systems, as it indicates the difficulty of the hardest single move. Due to this, it usually fails to show the overall difficulty of a problem, and since a single technical grade can span four or five overall grades, it is not usually used by boulderers.
British bouldering guides tend to use V or B grades although many problems, principally those of 8a or above, are also known by their Font grade. UK guidebook writers have primarily adopted V grades because they are more useful in grading easier problems. One minor adaptation of the V system you may encounter is the use of V8+, between V8 and 9, as the equivalent of Font 7b+.
