How to Plan Your Mega Tree Build
A Mega Tree is the centerpiece of any professional Christmas light show. Whether you are using traditional AC lights or modern RGB pixels (like WS2811), getting the geometry right is essential for a clean, symmetrical look. This calculator helps you determine the exact length of your light strings and the spacing required at the base ring to ensure your display looks professional.
Key Dimensions Explained
- Height: This is the vertical height from the ground to the top of the "topping flange" or hook head.
- Base Diameter: The width of your base ring. A common ratio for a pleasing aesthetic is a 2:1 ratio (Height to Diameter).
- Slant Length: This is the actual length of the string from the top of the pole to the base ring. It is always longer than the vertical height.
- Base Spacing: This determines how far apart each strand should be attached to your base hoop.
Example Calculation
If you build a 12-foot tree with a 6-foot diameter base using 16 strands:
1. The radius is 3 feet.
2. Using the Pythagorean theorem (A² + B² = C²), the slant length is √(12² + 3²) = 12.37 feet.
3. For a 360-degree tree, the base circumference is ~18.85 feet.
4. Your strands should be spaced 14.1 inches apart on the base ring.
Design Tips for RGB Pixel Trees
If you are using 12mm RGB Pixels, pay close attention to the Calculated Pixel Spacing. If your slant length is 12 feet and you have 50 pixels, your spacing is roughly 2.8 inches. If your physical wire between pixels is only 2 inches, your string won't reach the base! Always ensure your wire length is greater than the calculated spacing.
