A level ruler is often called a spirit level or bubble level. These tools combine a straight edge or ruler with one or more bubble vials to help you check if surfaces are horizontal (level) or vertical (plumb). Depending on the design, you might also hear terms like torpedo level, box level, or laser level. Each type is suited for different tasks, so it’s helpful to know these names when shopping for the right tool at Walmart.

You can turn your smartphone into a level by downloading a level app from your device’s app store. These apps use your phone’s built-in sensors to mimic a bubble level, helping you check if surfaces are straight. For simple tasks like hanging pictures or checking shelves, just open the app and place your phone flat against the surface. While convenient, phone levels may not be as accurate as dedicated tools, especially for heavy-duty projects. For precise results, consider using a physical level ruler from Walmart’s selection.

Not all rulers are 12 inches long. Standard rulers are usually 12 inches (or 30 centimeters), but there are many variations. You’ll find shorter pocket rulers and longer measuring sticks—some up to 16 feet or more for construction and surveying. Level rulers often come in different lengths to suit various projects, from compact torpedo levels to extended box levels. Always check the product description at Walmart to make sure you’re getting the length you need for your job.

A bubble level uses a liquid-filled vial with a bubble to show if a surface is level or plumb. It’s simple, reliable, and great for most home improvement tasks. A laser level projects a straight line or dot onto surfaces, making it easier to align objects over longer distances or across multiple points. Laser levels are handy for tasks like installing shelves or tiles. Both types are available at Walmart, so you can choose based on your project’s needs.

• Consider the length: Short levels are good for tight spaces, while longer ones help with bigger surfaces.
• Check for magnetic features: Magnetic levels stick to metal surfaces, making hands-free work easier.
• Look at the number of vials: More vials mean you can check multiple angles (horizontal, vertical, 45°).
• Think about durability: Aluminum or heavy-duty plastic are popular for lasting performance.
