The frame decides whether the vial still tells the truth in a year · review
Three levels at 40, 60 and 100 cm (39.4 in), and the only entry in this hub that publishes a turn-over figure — ± 0.75 mm (0.03 in) — which is the number that describes whether a level is telling the truth.
What the figures leave us with The set to buy first. It is not the best level of any length, and it is the only one here that publishes the figure a level should be judged on.
Three levels, one box, and the only turn-over figure published in this hub.
A three-piece set at 40, 60 and 100 cm (39.4 in). Three vials on each for horizontal, vertical and 45° measurement. A ground lower measuring face stated to reach ± 0.5 mm (0.02 in). Turn-over accuracy stated at ± 0.75 mm (0.03 in), described as constant and reliable measuring performance even when rotated through 180°.
Every level in this hub publishes an accuracy figure. Only this one publishes what happens when you check the level against itself. That check — read, rotate end for end, read again — is the only test a buyer can perform without a reference surface, and a level that fails it has an error that no amount of care can work around, because it is baked into the relationship between the vial and the base.
A maker willing to state a turn-over figure is stating what that check will show. It is the most useful specification on this page.
Bought separately, the best 40, 60 and 100 cm (39.4 in) levels here would cost several times this. What you give up is that none of the three is the best of its length: the Stabila’s bonded vials and the Bosch’s V-groove and scale are absent. For a workshop that currently owns no level, having the right length beats having the better tool of the wrong length.

It is the difference between what a level reads on a surface and what it reads after being rotated 180° in place on the same surface. A level can hold a perfect vial position and still be built with its vial slightly out of parallel to the base; the turn-over figure is the one that exposes it. Einhell states ± 0.75 mm (0.03 in).
A level reports the two points it touches. Too short and it reads a local bump; too long and it will not fit the space. Einhell states 40, 60 and 100 cm (39.4 in), which covers appliance leveling, general alignment and door frames.
Setting and checking mitres and diagonal bracing, where neither the horizontal nor the vertical vial applies.

Equipping a workshop from nothing, where owning the right length matters more than owning the best one.

20 cm (7.9 in) · 1 mm (0.04 in)/m stated · two vials · rubber end bumpers
A 20 cm (7.9 in) pocket level with ground bearing faces, a stated accuracy of 1 mm (0.04 in) per meter and rubber bumpers at both ends. The loosest published figure here, in the smallest and cheapest body.
Best for: The level that lives in a drawer or a kitchen cupboard for hanging pictures and checking appliances.
60 cm (23.6 in) · 0.5 mm (0.02 in)/m stated · V-groove · two marking sliders
A 60 cm (23.6 in) aluminum level stating 0.5 mm (0.02 in)/m, with fluorescent vials, a double metric scale that turns it into a rule, a V-groove for pipes, and two sliders for marking leveled points.
Best for: The general-purpose level for someone who would otherwise carry a level and a rule.
50 cm (19.7 in) · ± 0.5 mm (0.02 in)/m stated · locked vials · −20 to +50 °C (122 °F)
The level built around keeping its vials where they were set: Stabila states ± 0.5 mm (0.02 in)/m in the normal position, permanently bonded vials, and accurate reading from −20 °C (-4 °F) to +50 °C (122 °F).
Best for: A level that stays right. The bonding of the vials is the specification you are buying.
