Spirit Levels

A spirit level (also called a bubble level) is a tool used to check whether a surface is completely horizontal or vertical, using a liquid-filled vial with an air bubble as the indicator. Tradespeople including bricklayers, carpenters, electricians and plumbers rely on them for accurate, level work on site. Our range covers box beam, torpedo and digital spirit levels in sizes from 600mm to 1800mm.

Spirit Levels for Trade Professionals

A spirit level (also called a bubble level) is a tool used to check whether a surface is completely horizontal or vertical, using a liquid-filled vial with an air bubble as the indicator. Place the spirit level in the centre of the object you are levelling – the bubble in the vial will sit exactly between the two lines when the object is level; if it drifts too far to the left or right, you'll need to adjust the height at one end.

Spirit levels are essential tools for surveyors, bricklayers, contractors and tradespeople, including masons, woodworkers, carpenters, electricians and plumbers. Having the right spirit level on site can be the difference between a job done right first time and costly rework – which is why Tiger Supplies stocks a dependable range for businesses ordering individually or in bulk for a full team.

Types of Spirit Levels

Tiger Supplies' spirit levels are precision engineered to ensure maximum accuracy. They come in a variety of sizes, from small, compact torpedo levels for tight spaces up to long spirit levels for larger flat surfaces, mostly ranging from 600mm to 1800mm. Browse our full spirit level set below to find the right length for your job. We have a variety of spirit levels to suit your needs, including box beam levels, torpedo levels and digital spirit levels.

  • Box beam levels – versatile tools with a rectangular or box-shaped frame and handgrips for easy handling, ideal for measuring flat surfaces horizontally and vertically. Our box beam spirit level is made of lightweight aluminium with sturdy handgrips and shock-absorbing end caps to protect the level if dropped; the Stanley FatMax Pro Box Beam Spirit Level has solid-block acrylic vials to provide an accuracy of 0.5mm/m in eight orientations
  • Torpedo levels – this type of spirit level is usually shorter to level tight spaces where standard levels would not fit. Our Stanley FatMax Torpedo Level comes with a magnetic base and 3 vials, making it ideal for installing machinery, air conditioning ducting or shelving
  • Digital spirit levels – display the exact angle on a screen rather than relying on reading a bubble by eye, giving a precise numerical reading useful for tasks that need more accuracy than a standard vial, such as installing appliances or setting up machinery

Tips to Use Spirit Levels

Tip 1: Prepare your level before use

Select the appropriate model for the job. If it has been used before, clean it so that no material or dirt is present and remove any buildup from the edges.

Tip 2: Check your level is accurate

Mark a line along the bottom edge of the wall, then flip the level over so the bottom becomes the top and place the new top edge along the marked line. If the bubble is not centred, your level is defective.

Tip 3: Use it correctly for an accurate reading

Place the level on the surface of the object you want to measure, align your eyes with the tool (closing one eye can help you get an accurate reading), and check the bubble sits centred between the two lines. If it's off to one side, adjust the object accordingly.

Spirit Levels: Frequently Asked Questions

What is a spirit level used for?
Spirit levels are used to check that a surface, wall, or object is completely level (horizontal) or plumb (vertical) before fixing it in place – essential for shelving, tiling, flooring, and structural work.

How do I choose a spirit level?
Match the length to the job: shorter torpedo levels (around 230mm) suit tight spaces and pipework, while longer box beam levels (900mm–1800mm) give more accurate readings across walls, floors and worktops. For precision work, a digital spirit level provides an exact angle reading.

Can a spirit level be wrong?
Yes – vials can lose accuracy over time or after being dropped. Check yours by placing it on a surface, marking the position, then flipping it 180°. If the bubble reads differently in each position, the level needs recalibrating or replacing.

What can I use instead of a spirit level?
A smartphone spirit level app or a laser level can substitute in some situations, but neither matches the reliability of a traditional vial level for precision trade work.
