That depends on how big the object is, the time of year, and the location you are. obviously, the size would make a difference, the season determines the tilt of the earth changing the shadow length. if you were in Africa at midday, your shadow would be short since the sun is directly overhead. if you were in Antarctica at noon, the sun would be lower to the ground thus creating a longer shadow.

What affects was the size of a shadow?
The size of a shadow depends on, the angle that the light source is hitting the object and the size of the object. In some cases, the amount of light can also affect the size of a shadow.
What causes shadows to change size and direction during a day?
The angle of the earth to the sun changes the direction and size of shadows during the day. Since the earth rotates giving us night and day, the angle at which the suns light is hitting the earth(and you) determine the size/shape of the shadow
Why does the size of the shadow change in a day?
Because the sun's change in apparent motion across the sky results in a change in the angle of the shadow that is cast.
What is the difference between a shadow of an object created by a small light source and the sun?
Shadow from light source always bigger than object but shadow from the sun is the same size as object. Great different is due to the distance of light source. Size of shadow is double at distance x 2 source to object. Shadow is always bigger than object. You will notice your shadow is bigger in light bulb or stadium spot light but the shadow from sun is the same size as object. This is due to great distance from sun to us (150 million km approximately) the double distance to see our shadow to be double is at 300 million km from the Sun. at merely 10 m or 100 km is almost no distinguishable different in shadow size to the object. We then presume shadow cause from sunlight is equal to the size of the object.
When does the sun cast the shortest shadow?
At noon, or when the sun is in the middle of the sun is in the middle of the sky. It is directly above you so it casts arely any shadow. One could argue that it is shortest at night, when it is non-existent, but that technically means that there is no shadow to measure.
Why do we cast hardly any shadow in the middle of the day?
Because the sun is directly overhead.
Why shadow get smaller and bigger in a scientifically explination?
The size of a shadow has everything to do with placement of the light source, the object, and the background on which the shadow is cast. In general, if the light source is close to the object and the background is further away then the shadow is larger than the object. The opposite is true if the light source is further away. Another part of the equation has to do with angles. This is what we commonly observe happining to shadows at different times of the day; long shadows in the morning and evening and smaller shadows around the middle of the day.

Are shadow different sizes all the time?
The size of a shadow depends on the angle and distance if the light source and the size and shape of the object making the shadow. They can be the same size.

What is the size of the shadow and the distance of the object from the light source when a shadow is formed?
If you are using a point light source, the shadow's size is the object's size divided by the distance from the light source to the object multiplied by the distance from the light source to the shadow.
How big are shadow puppets?
Shadow puppets can vary in size depending on how they are made, but typically they range from a few inches to a foot in size. The size of a shadow puppet is determined by the distance between the light source and the screen where the shadow is being projected.
When was Shadow of the Day created?
Shadow of the Day was created on 2007-10-16.
How do shadows cast by the sun change in size through out the day?
It depends on the angle at which the light from the sun hits you. If its noon, you won't really have a shadow but if the sun is setting in the west, you will have a shadow towards the east.
How shadows change size during a day?
shadow will become short when it was xiawu and no shadow at night! haha At noon, when the sun aerial, and shadows is the shortest. When the sun goes down, the shadows change into the longest.
