Ender 3 V3 Ke Z axis dimension

When printed the object is shorter in Z axis . How can I modify the Z Steps ?

I know that in the Creality slicer you can adjust the Z axis height. You can leave everything to adjust at the same ratio OR you can unclick the box. Its the ratio button and you can adjust X,Y & Z independently or keep them adjusting all the same ratio. I don’t know if this is what you meant but that’s what I think. I took a model car body and adjusted it in the ratio, adjusting each the X,Y & Z independently till the measurements matched the body of an R/C car I wanted the body for. It came out perfectly sized for X,Y & Z (width, height & length)

hope this helps

Thank you for the answer. I use the Orca slicer, and the bed offset is adusted perfectly, but I tought that was a way to adjust the Z steps like in X and Y axis. I will try your aproach.
