A surgical stapler includes a handle assembly (10), a central body (14) extending distally from the handle assembly (10), an anvil assembly (18) and a cartridge assembly (16). The handle assembly (10) includes a stationary handle (22) defining a window (48) and a tissue gap indicator assembly (28, 150) that includes a slide (52, 152) that supports indicia (80, 180) that is visible through the window (48). The indicator assembly (28, 150) includes a lever (54, 154) which couples the slide (52, 152) to a drive screw (40) of the surgical stapler to translate movement of the drive screw (40) into movement of the slide (52, 152). The lever (54, 154) is configured and adapted to translate movement of the drive screw (40) over a distance of X1 into movement of the slide (52, 152) over a distance of X2, wherein X2 is greater than X1.
