Measuring for Replacement Tarps

Gable Tarp on Frame

A = Left rafter length
B = Right rafter length
C = Opening width
Measuring instructions:
  • A and B are measured from the peak of the canopy to the inside edge of the side rail tubing.
  • Tarps are sold in even foot dimensions however the actual size of the tarp will be 4 to 6 inches smaller.
  • Tarp Width = A + B and rounded to the nearest foot increment. If possible always measure the old tarp for replacement dimensions.
  • C is opening width, this is not the same as tarp width and should not be used when ordering a replacement tarp.
  • Tarp Length is measured from inside of the front rafter to the inside of the back rafter. Round to the nearest foot increment.  Always make measurements between the actual rafters and not the legs for accurate measurements. If possible always measure the old tarp for replacement dimensions.

Valance Tarps

Our Valance style tarps are measured as described above. Valance style tarps are measured only by the main part of the tarp, and the valance is extra - the main part of the tarp fits inside of the framework the same as a gable tarp and the valance is sewn to the top of this tarp and hangs over the gap and down the outside of the frame approx. 8 - 10".

Site Tarp

This is a tarp that is placed from the from the top side rail of a canopy to a lower horizontal rail to create a side on a canopy.
Measuring Instructions
  • Tarps are sold in even foot dimensions however the actual size of the tarp will be 4 to 6 inches smaller.
  • Tarp Width is measured from the top rail to the bottom rail.
  • Tarp Length is measured from inside of the front leg to the inside of the back leg. Round to the nearest foot increment. 
  • If possible always measure the old tarp for replacement dimensions.

Tarp Over Side

Tarp over side canopies use a single tarp to cover the top and part or all of the sides.
Measurement instructions:
  • A and B are measured from the peak of the canopy to the corner of the side rail tubing.
  • If canopy has lower horizontal rails then D and E are measured from the corner of the side rail tubing to the inside edge of the lower horizontal rail tubing.
  • If canopy does not have lower horizontal rails then D and E are measured from the corner of the side rail tubing down to the ground.
  • Tarps are sold in even foot dimensions however the actual size of the tarp will be 4 to 6 inches smaller.
  • Tarp Width = A + B + D + E and rounded to the nearest foot increment. If possible always measure the old tarp for replacement dimensions.
  • C is opening width, this is not the same as tarp width and should not be used when ordering a replacement tarp.
  • Tarp Length is measured from inside of the front rafter to the inside of the back rafter. Round to the nearest foot increment.  Always make measurements between the actual rafters and not the legs for accurate measurements. If possible always measure the old tarp for replacement dimensions.

How do I determine what type of peak I have?

Peak Measurements

A = Peak Rise in inches
B = Opening Width in feet
C = Over Top Width
Measuring Instructions
  • Measure "A", the total rise by drawing an imaginary line (or holding a string) from the corners of the canopy. In the middle of the measure from this line to the peak of the canopy. This measurement is in inches.
  • Measurement "B" is the opening width of the canopy. Make this measurement by measuring inside the vertical upright poles. This measurement is in feet.
  • Calculate the rise by dividing A by 1/2 of B. The equations looks like this: A / (B/2) . This will give the number of inches rise per foot in canopy width.
  • Low Peak Canopies are 2.5 in / ft.
  • Medium Peak Canopies are 4 in / ft.
  • High Peak Canopies are 7 in / ft.

How do I choose the correct Peak Drop tarp for my Canopy?

A = Peak Rise in inches
B = Opening Width in feet
C = Over Top Width
First determine the peak style of your canopy. For help go here.
Low Peak and Medium Peak:
  • Low Peak and Medium peak size should be picked to match the tarp over top width measurement "C".  The bottom measurement shown in the table should be a few inches smaller than your actual opening "B" to allow ball bungees to pull the tarp tight.
High Peak:
  • High peak size is selected by measuring tarp over top "C"  and subtracting 2 feet. For example if "C" is 12 feet then the order size for the Peak End Drop should be 10 feet. The bottom measurement shown in the table should be a few inches smaller than your actual opening "B" to allow ball bungees to pull the tarp tight.
