Spirit Levels
Shop spirit levels at MGN Builders Merchants for checking horizontal and vertical alignment on building, carpentry and renovation projects. Compare length, vial readability and frame construction to choose a spirit level suited to the job and available working space. Check individual product specifications for stated accuracy, vial positions and end-cap protection before buying.
Choosing the Right Spirit Level
Match the length of the level to the surface you need to check and the space available. A 600mm spirit level is practical for shelves, kitchen units and smaller building tasks where a longer tool may be awkward to position.
A long spirit level provides a longer reference when checking walls, door linings and timber framing. Options such as the 1800mm spirit level suit these larger surfaces. Consider weight and grip as well as length, particularly when holding the tool vertically or using it repeatedly throughout the day.
Accuracy, Vials and Handling Features
Compare the stated measuring accuracy, usually expressed in millimetres per metre, and the measuring positions covered by the specification. The horizontal vial is used to check level, while a vertical vial checks plumb. Clear vial markings and a readable bubble help when working in confined spaces or viewing the tool from different positions.
Features vary between spirit levels. The 1200mm spirit level, for example, has milled measuring surfaces, a magnified horizontal vial and cushioned handles. Consider these features alongside frame construction, grip and protective end caps when choosing a tool for regular site work or DIY projects.
Checking and Caring for Your Spirit Level
Keep the measuring face and the surface beneath it free from dust, grit and hardened mortar, which can affect how the tool sits. Before important work, or after a knock or drop, check the level for damage and confirm that its readings are consistent.
To check the horizontal vial, place the level on a firm, flat surface, mark its position and note the bubble reading. Turn it end for end, keeping the same measuring face down, and return it to exactly the same position. The bubble should return to the same position. If the readings differ noticeably, repeat the check and seek advice before relying on the tool.
Clean and dry the level before storage, and protect the frame and vials from impacts. For measuring distances, browse our tape measures. For checking right angles and transferring angles, explore our squares and bevels.
