When choosing a clear glass digital bathroom scale, consider the following factors:

1. Weight Capacity: Look for a scale that can accommodate your weight. Most bathroom scales have a weight capacity of at least 300 pounds, but some models can support up to 400 or 500 pounds.

2. Accuracy: The scale should provide accurate and consistent readings. Look for a scale with a high-precision sensor and digital display that shows weight in increments of 0.2 pounds.

3. Clear Glass Design: Choose a scale with a clear glass design for a sleek and modern look in your bathroom. The glass should be tempered and durable enough to withstand regular use.
   

4. Easy to Read: Look for a scale with a large and easy-to-read digital display. The display should be backlit for easy reading in low-light conditions.

5. Auto On/Off: A scale with an auto on/off feature is convenient and helps to conserve battery life. The scale should turn on automatically when you step on it and turn off after a few seconds of inactivity.

6. Low Profile Design: A low-profile design is ideal for a bathroom scale. The scale should be thin and lightweight, making it easy to store and move around as needed.

7. Price: Clear glass digital bathroom scales can range in price from around $20 to over $100. Consider your budget and choose a scale that fits within your price range.

By considering these factors, you can choose a clear glass digital bathroom scale that is accurate, easy to read, and adds a modern touch to your bathroom decor.
