That all depends upon what time of day the shadow was cast. For example, at straight up noon, even a very tall building wouldn't cast much of a shadow, but at sunrise or sunset, even a tiny building might cast an 18 foot long shadow, or even longer.
Noon in winter, 1pm in summer when clocks are an hour ahead of Nature.
Some very wise man noticed that the shadow cast from a stick placed vertically in the ground was a different angle at exactly noon than the angle of shadow cast at exactly noon from a vertically placed stick in the ground at a location further north. By employing mathematics, he was able to deduce that the earth is in fact, roundish.

The shortest shadow occurs at noon.
shadow
the shadow would be longer in the winter i couldn't tell you why, though
local noon (not noon according to the clock)
There will be no shadow because the sun will be directly over your head on the equator at 12 noon.
The shortest shadow is cast at noon when the sun is directly overhead, resulting in the smallest angle of incidence for sunlight and the shortest shadow length.
at noon the shadow is point sized {smaller} and in morning and evening the shadow is the longest.
If you spend enough time standing around, during a sunny day, watching your shadow, you can observe that it will quite long early in the morning, and it gradually gets shorter as you approach noon; after noon it starts to get longer again. Then at night time, it is gone. Although moonlight can also cast a shadow, much fainter than the shadow you can get with sunlight.
At mid-day or when the sun is as close to overhead of you as possible. At this time, your shadow will be directly below you and not long, as it is at sunrise or sunset. If you want which day in a year the Shadow likely to be smallest than it is June 22
Noon, because the sun is directly overhead.
