The Best Levels

Types of Levels

• Spirit Levels (Bubble Levels): These are the most common type, featuring vials with liquid and a bubble. The bubble's position between marked lines indicates if a surface is level, plumb, or at a specific angle. They come in various lengths, suitable for different tasks.
• Laser Levels: These project a laser line onto surfaces, offering a highly accurate and visible reference point. They are ideal for larger projects, installing cabinets, or when a long, straight line is needed. Some models can project horizontal, vertical, or both lines simultaneously.
• String Levels: A simple and inexpensive option, these consist of a string with a plumb bob and a vial. They are useful for establishing a level line over long distances where a spirit level would be impractical.
• Digital Levels: These offer precise digital readouts of angles and slopes, often with audible alerts. They are excellent for tasks requiring very high accuracy, such as setting up machinery or precise framing.

Key Features to Consider

• Accuracy: Look for levels with a stated accuracy (e.g., 0.029 degrees). Higher accuracy is crucial for critical tasks.
• Vial Visibility: Ensure the vials are clear, well-marked, and easy to read, even in low light conditions. Some vials are illuminated or use high-visibility liquid.
• Durability: A robust frame, often made of aluminum or reinforced plastic, will withstand job site wear and tear. Shock-absorbent end caps can also protect the level.
• Length: Shorter levels are good for general use and tight spaces, while longer levels provide greater accuracy over longer spans.
• Magnets: Magnetic edges are useful for working with metal surfaces, such as pipes or studs.

Choosing the Right Level for Your Project

• General Home Use: A 24-inch spirit level is a versatile choice for hanging pictures, shelves, and minor repairs.
• Framing and Construction: Longer spirit levels (48 inches or more) offer better accuracy for walls and larger structures. Laser levels are excellent for ensuring consistent heights and alignment across rooms.
• Plumbing and Electrical: Compact spirit levels or digital levels are useful for tight spaces and precise angle measurements. Magnetic levels are beneficial when working with metal conduit or pipes.
• Large-Scale Projects: Laser levels are indispensable for establishing level lines over extended areas, such as decks, patios, or landscaping.

Comparison Tips

• Compare the number and orientation of vials. Most spirit levels have three: horizontal, vertical, and 45-degree.
• Check the frame material and construction for durability.
• Consider the ease of reading the bubble or laser line in various lighting conditions.
• For laser levels, note the range, beam visibility, and any self-leveling capabilities.
