Jamb depth?

Hi Newbie here...I Thank you for the help you all be giving me..

I got 100 yr old 2 family house I decided it time to put in vinyl replacement windows..
I just doing one in the back at this time to make sure it is something I can do.. I had to change out a rotted sill (I'll call it the middle sill) I done that, and that turn out real well and so I order a new replacement window to install..(not here yet)

The question is...When I order the window I didn't think about the Jamb Depth.... I was looking at the new window Spec. Sheet and the Jamb depth is 2.625" and the existing window jamb is 3.25"... So am I going to have a problem when I install this window?? Also when I continue and do the other windows should I order the windows with 3.25" jamb depth instead?? Thanks

I dont know if you are using a higher end brand or a low end brand from home depot or lowes but most new replacement windows are 3 1/4.

this post should be on the "do it yourself" section.

A window with a 3.25" jamb depth will make the install much easier, using a higher quality window will make it even easier. Choose wisely.
