Abstract: The disclosure provides a microfluidic chip, a droplet generation device and a method for controlling a droplet generation size. The microfluidic chip includes a substrate and a first flow channel, a second flow channel and a third flow channel distributed on the substrate, the first flow channel, the second flow channel and the third flow channel intersecting to form a confluence area, the first flow channel being configured for a flow of a dispersed phase fluid from it, the second flow channel being configured for a flow of a continuous phase fluid from it, the dispersed phase fluid and the continuous phase fluid forming droplets in the third flow channel. The dispersed phase fluid flows in the first flow channel along a first direction, an orthographic projection of the first flow channel on the substrate has a first width which is constant in a second direction.
