Let’s get right to the point. How much light do you want coming through the Blind?
If you want to control the amount of light coming through your windows throughout the day, Venetian Blinds will allow you to do so. You can adjust the amount of light by opening and closing the blades, however rays of light may still slip through.
With Roller Blinds you can shut out the light completely during the day and night, or roll them up leaving you open to the world outside.
Both Blind options will offer complete privacy, but with Venetian Blinds you can be semi-private and still have some light into your room.
