Abstract: A telescopic leveling instrument has a small and light-weight bubble-level block (1) with orthogonal walls that include a rectangular first end (3) and a rectangular second end (4) from which telescopic markers are extended. The telescopic markers can include circular telescopic tubes (2), square telescopic tubes (11) or rectangular telescopic tubes (12). The bubble-level block is articulated to be finger-held with a first hand of a user for positioning it against an object while with a second hand, the user is utilizing the telescopic markers for measuring and marking a desired position selectively in relationship to the object against which the bubble-level block is being held. Attachable to extendable ends of the telescopic markers can be a selection of marking aids (17, 18, 19, 20, 21, 22, 23, 24). Preferably, the telescopic markers are ruled with distance indicia for fine measurement.
