For objects which are around 3 metres in front of the lens , the 50mm means one camera will have its image 1.6% larger than the other camera's image. It is normal to make alignment corrections between left and right image using software on a PC. This is free software - StereoPhotoMaker. It can easily adjust for the different in image sizes and other difference such as tilt which occurs between the two cameras. There are also manufacturing differences between lens which can result in different image sizes.

What about the size of distant objects? Still 1.6% larger?

This method of getting the two lenses closer is not perfect. In practise I find it does not cause a significant problem.
