What Size And Configuration of UPVC Windows Do Overseas Buyers Prefer

When communicating with overseas clients, you’ll notice a very practical issue: buyers don’t just care about price—they care more about whether the size fits their market, whether the configuration sells well, whether shipping is efficient, and whether installation is easy.

For a Chinese supplier like VIGORAWINDOWS, if you understand in advance the preferences of different markets for uPVC window sizes and configurations, you can not only improve inquiry conversion rates but also reduce repeated communication costs.

This article will clearly and simply explain real buyer preferences and, based on our export experience, show which sizes and configurations are easier to sell.

Common uPVC Window Size Preferences in Overseas Markets

Different countries have different building habits, but in actual export business, we have summarized some high-frequency standard size ranges:

1. Common Size Ranges (Suitable for Most Markets)

Width: 600mm – 1500mm

Height: 600mm – 1800mm

Small windows (bathroom/kitchen)

600 × 600mm

800 × 800mm

Medium windows (bedroom/living room)

1000 × 1200mm

1200 × 1500mm

Large windows (floor-to-ceiling/balcony)

1500 × 1800mm or larger

These sizes are very common in the Middle East, Africa, and Southeast Asia because:
