alm36 on "Enlarging Logo Size in Header"

In the openstrap theme on my website, there is an option to add your own logo to the site. I did so, but it is much too small. When I try enlarging the logo in the code, it makes the whole page too wide with a big empty section on the side.

Here is the only logo-related code I can find (in the CSS):

.logo-row{
#margin-bottom:10px;
#max-height:173px;
height:130px;
max-height:130px;
padding-top:5px;

}

I tried just adding "width:1600px" which made the logo itself large enough but the page too large as well.

Please please help me out, thank you!!!
