You can do this several ways:

Highlight a bunch of consecutive rows; then select the bottom border of the topmost row and drag it down manually. All the selected rows should resize to the same height.

Select any number of rows or cells (to select non-contiguous rows, hold down the Control key and cherry pick several cells), then go to the Format dropdown on your Home Ribbon, select Row Height, and input the numeric value you want for those row heights.

If you're doing that adjusting over and over again, you'll want to create a template for that type of spreadsheet that requires the logo, or record or write a macro with those steps. You can assign a button on your QAT to that macro and adjust new sheets with the push of that button.
