First what is it you need from the window coverings for sure not what you have obviously. I use solar shades if heat and UV are an issue and the bonus is you get to keep the view and have daytime privacy . If night time privacy is a big issue then I pair those blinds with drapes nice full ones that still look nice when closed . Take a much better pic of the whole room where this window is with the lights on inside to get more exact help.

Budget $200, $500, other? Three cellular or accordion blinds would work. Online estimators are easy to use.

For a stylish setup, having shades per window could add a balanced and visually appealing look. Do you have any specific styles or colors in mind that you’d like to match with the room's decor?

If you'd like, I can also offer some general tips on measuring to get the perfect fit for each window.

I had a window that large and had to select a large shade for the center window and two matching shades for the side windows. I did an inside mount.
