2.2. Weight & Size

---

Quick Theory

Drone weight and size calculations are based on the following formulas:

Minimum Frame Diagonal Calculation

$F_{min} = \sin(\pi/n) \times (D + c)$

Disk Loading Calculation

$DL = \frac{m \times g}{n \times \pi \times (D/2)^2}$

Symbol	Description	Unit
$F_{min}$	Minimum Frame Diagonal	mm (millimeters)
$D$	Propeller Diameter	mm (millimeters)
$c$	Propeller Clearance	mm (millimeters)
$n$	Number of Motors/Propellers	count
$DL$	Disk Loading	N/m² (Newton per square meter)
$m$	Drone Mass	kg (kilograms)
$g$	Gravitational Acceleration	m/s² (approx. 9.81)

The Weight & Size Calculator offers Standard and Advanced options for users to choose from.

Regardless of the option selected, the weight and size calculation results provide the following information:

• Minimum Frame Diagonal [mm]
• Disk Loading [N/m²]
