Most people undersize their columns, creating a pole effect
on a porch or deck area.
It is important to maintain a design ratio between the
columns size and the house or office as seen in the photo.
Simple Answer:
For modernism Non-tapered will look like posts. This provides a simple look
to a facade or deck structure.
For a traditional look use Tapered Columns.
The taper provides the visual distortion necessary for the column to look proper.
Keeping within the design principles of PHi, ie "the golden rule" there should be approximately
a 1/3rd to 2/3rd ratio variation between the top of the column and the bottom diameter.
Example: Top diameter of the shaft is 10", the bottom is 16", height 10 Feet
The taper should stop 2/3rds down the shaft, then go straight to the bottom.
This can vary per manufacturer. On a 10 Feet high shaft the taper would stop
approximately at the 7-1/2 Feet level. Using the calculation of Phi .618 the taper
would stop at 6.18 Feet level, then go straight. The use of the 2/3 - 1/3 rule
is mostly used by manufacturers rather than true Phi.
Regardless of species, any hardwood column can be

custom made.
You can
a) Specify the exact height within 1/8"
b) Specify the diameter on round columns
c) On tapered columns specify the Entasis or variance
between the top of the shaft and the bottom of the shaft.
Most columns are made to a 2/3rd taper and a 1/3rd straight
to the bottom.
d) Split hardwood columns can be ordered for post wrap
or pilaster (engaged) column applications.
Remember the walls are approximately 1-1/2" thick on
either side when considering post wrap.

Load bearing columns are those that are Whole and NOT split for reassembly or pilaster applications. Once split they cease to be load bearing.
If the columns are sold as load bearing they are rated by the manufacturer and all static and non static loads should be assessed by the architect or structural engineer. Always have your project inspected by the City.
It is vital during placement of the shaft that it is placed directly DEAD CENTER to the dead load applied (ie the lintel).
Load is borne on the shaft not the capitals or bases as the free float. Any variation to the application center load will subject the column shaft to an uneven amount of weight on one side of the shaft resulting in possible breakage or cracking.
Also ensure that 100% of the bottom of the shaft is sitting evenly on the substrata.
PVC column wraps historically take a while to be installed due to the amount of cutting, mitering, gluing, and setting that needs to take place. SnapTite™ PVC Columns were recently introduced and presented a time-saving alternative that did not sacrifice the desired style.
