Metric Pavilino Calculations

This will do all the (metric) calculations for determining the correct measurements for a pavilino (using canvas that is wide enough for a single wall section), without having to struggle through the math.   If you are using narrow fabric, figure out the width you will be using (after you sew pieces together) and use that calculated width.  Click here for the US Measurement calculator.

You should only enter numbers in the green boxes and click the "Compute Values" button.  All dimensions are in centimeters. 

The dimensions calculated here do NOT include seam allowance.  Sewing flat fell seams the way I do it, you should allow 2 cm of seam allowance (on each side), which would reduce your canvas width by 4 cm.

Canvas Width (in cm) :

Number of spokes :

 Radius at the hub/eaves (in cm) :
(This is also called the "spoke length" but is the length from the spoke tip to the hub center when the spoke is in the hub.)
This distance should be at least 61cm shorter than the radius at the ground.  If it doesn't come out that way, change the value and re-compute.
I like 61-76 cm shorter than the ground radius

Height at hub/eaves (in cm) :

or

Radius of tent at the Ground  :

 cm
Vertical Height of Loft (From eaves to top of tent) cm
Base (Width of bottom of trapezoidal wall segments): cm
Top (Width of top of trapezoidal wall segments
and the bottom of the roof triangles): 		cm
Apparent Wall (Apparent height of wall trapezoid): cm
Apparent Roof (Apparent length of the roof triangle): cm
True Wall (True height (fabric length) of wall trapezoid): cm
True Roof (True (fabric) length of the roof triangle): cm

When I sew a pavilino, I make my doors by splitting each door panel in half, and sewing some of the strip that is "left-over" (from cutting the roof pieces out) onto one half, so I now have the front half overlap the back half (because the back half has the extra strip sewn onto it).  The other option is to use two complete wall sections that overlap.  The overlapping sections are folded back part way, with toggles and loops added, but they still overlap a few feet.  If you use this second option, you will need to cut two extra wall sections.  This is important to understand when using my "Total Material Required Calculation" below.

It is also important to understand that my total canvas calculations are not the same as Sorcha's because we lay out the canvas differently.  You CANNOT use my calculations for total amount of canvas, and then use Sorcha's layout.  Follow this link to see the way I layout (and cut) my canvas.
