Opinion by
Me. Justice Walling,The defendants, Strawbridge & Clothier, have a large department store on Market Street, Philadelphia, wherein the plaintiff, Mrs. Chapman, a customer, was hurt by a fall on March 9, 1921. This suit was for the injuries thereby sustained, on the allegation that they resulted from defendants’ negligence, as hereinafter stated. The jury found for the plaintiffs, and, from' judgments entered thereon, defendants brought these appeals.
The request of defendants for binding instructions should have been granted. A storekeeper, while required to use ordinary care to keep his place of business in a reasonably safe condition so as not to expose his customers to unnecessary dangers (29 Cyc. 453; Woodruff v. Painter & Eldridge, 150 Pa. 91; Robb v. Niles-Bement-Pond Co., 269 Pa. 298), is not liable for accidents they may therein sustain, except upon proof of his default: Huey v. Gahlenbeck, 121 Pa. 238. Plaintiff attempts to supply such proof by showing a defect in a marble step as the cause of her fall. There is a ladies’ rest room in the store and leading from there up to the retiring room is a flight of five marble steps, each with a fourteen-inch tread and a seven-inch rise. Plaintiff fell as she was descending these steps, she avers as the result of her foot sliding into a depression, three or four inches in diameter, worn in the third step. The steps, however, are still in place and, according to the evidence of disinterested witnesses who had examined and measured them, disclosed no such defect and no depression exceeding one-sixteenth of an inch in depth. Plaintiffs’ son, who made measurements there soon after the accident, testified that it took the thickness of fifteen pennies (practically seven-eighths of an inch) to bring the front of the step up to the level of the back or what he calls the heel of the step, and that from this line to the bottom of the *397so-called depression was slightly over seven-eighths of an inch. But that throws no light on the depth of the depression, as the line from which he measured was seven-eighths of an inch above the surface of the marble at the front edge. The evidence is that these steps were constructed with the usual incline forward, which fact was ignored by plaintiffs’ son when making his measurements. His testimony seems to have been understood at the trial as indicating a depression in the marble step of at least seven-eighths of an inch, but he did not so testify. What he said was: “I ran one end of the level — it started at the rear of the step, and built it up with pennies in front of the step until it became level, and then I measured the depth of the whole from the level of the rule to the bottom of the hole.” He does say, the way he measured it the hole was seven-eighths of an inch deep, but explains how he measured it, as above stated, which fails to prove an actual hole in the marble of that depth, nor is there evidence of any measurement showing such depression. True, a witness who merely looked at the steps says the hollow might have been an inch or an inch and a half deep, but also says she does not know much about inches and might not be right within a half inch or an inch. Such uncertain estimates cannot prevail against actual measurements. The steps were of American marble, properly constructed and in perfect condition, except slightly worn, and to hold defendants liable for this unfortunate accident would practically be to render the storekeeper an insurer of the safety of his customers, which he is not.
There was a hand rail around the opening at the top but none down the side of the steps; as they were less than three feet high, no inference can be drawn that the absence thereof created an unsafe condition, while the only testimony on the question was to the contrary. On the whole record the evidence is not sufficient to support the charge of negligence against the defendants. Of course, storekeepers are liable where they carelessly expose their *398customers to real dangers, like open elevator shafts, open hatchways, or obstructions in aisles, etc., but the decisions so holding are not parallel to the present case.
The judgments are reversed and are here entered for the defendants non obstante veredicto.
