'Aligning' objects

Hey guys!

I put the marks around aligning cause I already tried to align them, using the align objects tool but they’re still slightly off. I also tried moving them to the same exact area but I realized they’re slightly different sizes.

I guess I’m trying to fit them to each other.

Basically I have a box and a border I want to put around it. Is there any way to make the model shrink down in size in order to fit the box?

What does this exactly mean.

Please make some effort in clearly showing what you have and what you want to achieve.
Where are images, screenshots, your current blend file.
You’re making people have to guess what you are thinking of !! We’re not mind readers so please make more of an effort when asking for help

The rules said I’m not allowed links until I’m off probation or whatever.

It’s a box. It’s three dimensions. There is four rectangles in a single mesh that make a ‘border’ for the box that I want to fit around.
