Understanding 1:350 Scale
The 1:350 scale is a proportional ratio where every 1 unit of measurement on your drawing, model, or plan represents exactly 350 of those same units in the real world. This makes 1:350 a medium-scale representation, meaning objects appear moderately sized on paper.
For example, 1 mm on a 1:350 drawing represents 350 mm (35.0 cm) in reality. Conversely, a real-world measurement of 1 meter would appear as 2.86 mm on a 1:350 scale drawing.

How to Convert 1:350 Scale Step by Step
- 1Identify the scale ratio. You are working with 1:350, which means the drawing is 350× smaller than reality.
- 2Real → Scaled: Divide the real measurement by 350. Example: 5 m = 14.3 mm on paper.
- 3Scaled → Real: Multiply the drawing measurement by 350. Example: 20 mm on drawing = 7,000 mm (7.00 m) in reality.
1:350 Scale FAQ
- What does 1:350 scale mean?
- A 1:350 scale means that 1 unit on your drawing or model represents 350 of the same units in real life. For example, 1 mm on a 1:350 drawing equals 0.35 m in reality.
- How do I convert real measurements to 1:350 scale?
- To convert a real-world measurement to 1:350 scale, divide the real measurement by 350. For instance, a real wall that is 5 meters long would be drawn as 14.3 mm on a 1:350 drawing.
- How do I convert 1:350 scale back to real size?
- Multiply the measurement on your 1:350 drawing by 350 to get the real-world size. If something measures 20 mm on your drawing, the real size is 7,000 mm (7.00 m).
- What is 1:350 scale used for?
- The 1:350 scale is commonly used in model & miniature applications. It is ideal for representing objects and spaces at a manageable size while maintaining proportional accuracy.
- Is 1:350 scale metric or imperial?
- Scale ratios like 1:350 are unit-independent — they work with any measurement system. Whether you measure in millimeters, centimeters, inches, or feet, the ratio remains the same: 1 unit on paper equals 350 units in reality.
