The Tree Council recommend a quick calculation for ageing a tree as:

Measure girth in cm at chest height (1.5m from ground) and divide by

Trees in Woods     or               Solitary Trees
1.88                                               2.2
Oaks, Sweet Chestnut & Lime
2.5                                                 3.2
Hazel, Ash, Elm & Beech
2.75                                               3.5
Sycamore
1.25                                               1.75
Holly
3.13                                               4.0
Pine or Spruce

Walnut isn't mentioned but I would guess that the Oak etc category would
suffice.
