- Measure from multiple points (top, middle, bottom).
- Record both inches and cm for accuracy.
✏️ Pro Tip: Don’t measure only the glass—measure the full frame opening.
Window Styles Based on Size
Your choice of window style should match both size and use. Here’s what works best:
- Casement windows – Great for narrow but tall windows
- Sliding windows – Perfect for wide spaces
- Fixed windows – Best for large feature walls
- Awning windows – Ideal for above the stove or sink
💡 Make sure to leave enough space around your cabinets and countertops.
When to Go Big with Kitchen Windows
Bigger windows can bring in stunning natural light. They’re great for:
- Open-concept kitchens
- Scenic backyards
- Homes with limited wall cabinets
But make sure your wall structure supports the size. You may need header beams or reinforcements.
Specialized Window Use Cases (Stove, Expo, Opening Types)
- Windows above a stove: Use awning or casement windows, typically 40–60 cm in height and 120–160 cm wide for ventilation and light.
- Expo window with shelf: Often used in open kitchens or service counters. Mounted at 105–120 cm from the floor with shelf depth of 30–40 cm.
- Minimum size for opening windows in open kitchens: Ideally at least 60×90 cm (0.6×0.9 m) for safety and cross-ventilation.

Eye-level kitchen windows are often placed 105–110 cm above floor level and can be 100–130 cm wide.
Expo or pass-through kitchen windows are typically mounted 105 to 120 cm (1050–1200 mm) from the floor to align with counter height. If a shelf is included, it’s usually installed directly below the window, with a depth of 30 to 40 cm. While the shelf doesn’t affect the window’s height, the combined setup provides a functional and visually aligned serving space.
The phrase “24 by” often refers to width and height in inches, such as 24” x 36” or 24” x 48”, which are common for small to mid-sized kitchen windows. However, “24 by” isn’t a fixed standard—sizes vary by window type and placement (e.g., over the sink or as a side window).
In window terminology, “length” is usually referred to as height or width. For kitchens, standard heights range from 36 to 48 inches (or 900 to 1200 mm), while widths typically range from 24 to 48 inches (600 to 1200 mm). So if you’re asking about “window length,” consider whether you mean height (vertical) or width (horizontal) for accurate planning.
Final Thoughts
The right kitchen window size makes all the difference.
Whether you go for wide or narrow, tall or small, choose a size that balances function and design.
Measure carefully, follow local standards, and enjoy a brighter, better kitchen.
