How can I precisely set the same size of the slam map generated by (gmapping, Hectorslam, Kartoslam and chartographer)

edit

Hello,

When in use gmapping, Hectorslam, Kartoslam and chartographer package to create a map it makes a very small map (see images). The Kartoslam map is bigger then oder slam map.I don't know why ?

1. How can I precisely set the size of the slam map generated by (gmapping, Hectorslam, Kartoslam and chartographer)

In attachement you find the generate SLAM map and the launch files

I would appreciate an answer.
