Mailbox swag garland
Estimate garland feet for a mailbox post wrap and top swag from post height, wrap turns, and mailbox top length.
wrap_ft = π × post_diameter_ft × turns · swag_ft = top_length_ft × drape · total = wrap + swag + spare
When to use
This tool helps when you want a mailbox swag garland planning figure with the assumptions written down. You will enter post wrap height (feet), post diameter (inches), wrap turns (spirals up the post), and mailbox top / lid run (feet).
Estimate garland feet for a mailbox post wrap and top swag from post height, wrap turns, and mailbox top length. Keep units consistent (feet vs inches, watts vs amps), then use the formula box to see how each term contributes.
Stop and ask a licensed electrician when loads, hardwired outlets, or roof work go beyond temporary plug-in holiday displays.
From ground clearance to underside of mailbox.
Tighter pitch = more turns for the same height.
1.0 flat; 1.3–1.6 for a draped swag.
Worked example
Example inputs from the form defaults — Post wrap height (feet) = 3.5; Post diameter (inches) = 4; Wrap turns (spirals up the post) = 6; Mailbox top / lid run (feet) = 1.75; Top swag drape factor = 1.4 — are plausible homeowner figures, not a survey of your roofline.
Compute with: wrap_ft = π × post_diameter_ft × turns · swag_ft = top_length_ft × drape · total = wrap + swag + spare. Show intermediates before the final count or cost.
When the calculator and scratch math disagree, fix units first; the mailbox swag garland model is only as good as consistent inputs.
Limits / assumptions
Assumptions: inputs match the hints (measured eaves, nameplate watts, package strand length, and so on). Terms not named in the formula are not secretly included.
Limits: outdoor weather, GFCI trips, and real stock sizes vary. Prefer outdoor-rated cords and clips; ladder and roof work need their own safety practices.
Responsibility: confirm safety-critical electrical and height decisions with manuals and, when needed, a qualified professional. PWC Lights does not stamp displays.
Keep garland clear of the mailbox door and carrier path. Use outdoor ties; do not block reflective numbers required by local rules.
FAQ
Round vs square post?
For square posts use the face width as an approximate diameter stand-in, or measure circumference with string and divide by π.
How many turns?
Count how many times you want the garland to spiral; height ÷ desired pitch also works.
Bows?
Add ribbon separately with the wreath bow tool; this page focuses on garland length.
Already have garland-length?
That hub tool covers stairs/mantels; this one is mailbox-post specific.
