About running a stereo camera calibrator

I have two questions to ask.

I am the following site

https://jp.mathworks.com/help/vision/ug/depth-estimation-from-stereo-video.html

I would like to build a 3D scene using the stereo camera calibrator app with reference to. So which product should I use for a stereo camera that supports this site?

What size should I use for the checkerboard paper to be used?

In general, you can use any type of stereo camera and calibrate its intrinsic parameters using the Stereo Camera Calibrator. You are free to select the size of the checkerboard. When you import stereo images to the app, you will be asked to specify the size of the checkerboard; see Add Image Pairs.

I used Zed stereo camera and found that good point clouds were reconstrucetd with MATLAB. Zed offered the MATLAB code for the camera and you can easily test it.
