Choosing the right slat size for your blinds can dramatically impact how your windows look and function. While slats might seem like a small design detail, the size and material you choose affect light control, privacy, energy efficiency, and even the overall aesthetics of your home.
This guide breaks down how to choose the best slat size for small, medium, and large windows — plus expert tips on vertical blinds for sliding doors, installation, maintenance, and design.
🪟 Small Slats for Small Windows: Compact, Clean, and Light-Controlling
If you’re covering a small window, smaller slats (around 1 inch) are your best bet. They provide proportionate balance and subtle style without overwhelming the space.
✅ Benefits of Small Slats
- More slats = better light control and increased privacy
- Fits snugly in narrow window frames or sills
- Creates a refined, minimalist look
Because there are more slats per blind, your view will be slightly limited when the blinds are open—but you can simply raise them fully to enjoy an unobstructed view.
