How Small Can a Drone Be?
A drone can be as small as the size of a large coin. One of the world’s most popular and smallest four-propeller drones measures just 1.8 inches x 1.8 inches. This model is the HUBSAN H111 Nano Q4 and demonstrates just how small a drone can be these days.
This incorporates minimal electronics such as a 2.4 GHz transmitter, a 3.7 V LIPO rechargeable battery, and other additional items. While larger drones do exist, the truth is that there are no drones that are much smaller than this model.

What Makes a Drone So Small?
To answer this question, we must consider the components of a drone. What makes a drone small is the weight of each of its pieces around the internal motor force.
Exactly the ratio of the force the motor can exert along with the propellers to the unit’s total weight is what determines the size of a drone.
The aspect that allows these drones to be small is that they can fly for a limited time despite tiny motors and propellers. A small drone motor can fly despite the small and lightweight components. (1)
How Much Fly Time Can a Small Drone Have?
One of the main weaknesses of small drones is undoubtedly the flight time. When we talk about the tiny drones with dimensions of about 2 x 2 inches, the flight time is not very extensive. Most of them only provide 5 minutes or 10 minutes of flight time at best.
This is mainly because it is impossible to incorporate too large a battery inside the small drone. Small drones can fly due to maintaining a balance between the power of the Small motor and its lightweightness. Adding a more extensive battery means adding more weight, preventing the drone from flying. (2)
Are Small Drones Expensive?
Small drones do not require a large budget due to the small number of materials necessary for each drone. Considering the HUBSAN H111 Nano Q4, we have mentioned that these days they are less than $20. This model does not incorporate a camera in its structure which also makes it cheap.
It is also possible to find other options that require a higher budget due to the more advanced technology they incorporate. A high-resolution camera is included, which increases the costs.
