How to Choose the Right Force (N) for Your Cabinet Gas Spring?

When upgrading kitchen cabinets or designing custom furniture, one of the most critical yet confusing components is the gas spring (gas strut). If the force is too weak, the door won't stay open; if it's too strong, closing the cabinet becomes a workout.
In this guide, we will break down how to calculate the correct force (measured in Newtons, N) to ensure your cabinets operate smoothly and safely.
1. Understand the Unit: What is Newton (N)?
Gas springs are rated by their extension force, measured in Newtons (N).

Quick Rule of Thumb: 10 Newtons (10N) is approximately equal to 1kg of lifting capacity.
For example, a 100N gas spring is designed to support roughly 10kg of weight at a specific leverage point.

2. The Basic Calculation Formula
While professional engineers use complex software, you can estimate the required force using this simplified formula:

• F: Required Force in Newtons (N).
• W: Weight of the cabinet door (kg) multiplied by 10 (to convert to Newtons).
• L: Height of the door (from hinge to the bottom).
• D: The horizontal distance from the hinge to the gas spring mounting point.
• K: Safety factor (usually 1.1 - 1.3).

Pro Tip: If you are unsure, it is better to provide us with the door weight and dimensions, and our engineering team will calculate it for you for free!

3. Common Force Standards for Cabinets
Based on our years of manufacturing experience, here are the most common configurations for standard kitchen wall cabinets:
• 50N - 60N: For small, lightweight wooden doors.
• 80N - 100N: The "Standard" choice for most medium-sized kitchen cabinets.
• 120N - 150N: For heavy solid wood or wide glass-framed doors.

4. Factors to Consider
• Hinge Type: The friction of different hinges affects how much work the gas spring needs to do.
• Mounting Angle: The position of the mounting brackets significantly changes the effective lifting power.
• Environmental Temperature: Gas springs use nitrogen; extreme cold can slightly reduce the internal pressure.

Conclusion
Choosing the right force is about balance. Using a gas spring that is too powerful puts unnecessary stress on your hinges and cabinet frame, potentially leading to damage over time.
