If you are using a compact camera, digital or otherwise, the lens probably has no markings you can use. In this case, you will have to obtain a depth of field chart. If the camera has a depth of field scale on top of the lens barrel, you locate the f stop (the number) being used for the shot on both sides of the center dividing line and estimate the corresponding distances that line up with those numbers to get the depth of field as a range in feet or metres.
Describing this in words is virtually impossible, so the best I can suggest if you did not grasp the above, is to read up on it in your camera manual or Google it.
The size of the zone is determined by three key factors:-
the aperture of the lens, the focal length of the lens used, and the distance you are from the subject. Varying these three elements allows you almost complete control over the depth-of-field in a picture. So theoretically if you change any of these three factors then you change the field-of-depth

If you are changing the shutter speed why is the depth of field being affected?
Usually, one would change the aperture to compensate for the change in shutter speed in order to keep the level of exposure the same. Changing the aperture affects the depth of field.
What is depth of field best demonstrated with?
Depth of field is best demonstrated with a slide containing overlapping threads. The depth of field that would increase is the low power objective.
What is the difference between maximum depth of field and shallow depth of field on a camera?
Depth of field in photography is 3-dimensional and is measured from the foreground moving along a horizontal plane towards the background. Maximum depth-of-field means most of the scene is in focus and shallow depth-of-field means the minimum is in focus. Shallow depth-of-field lets you lose the background into a nice blur leaving the foreground in focus - good for portrait photography. In landscape photography you would normally choose the maximum depth-of-field so that distant hills were in focus as well as the middle ground and the foreground - in other words, everything in the field of your vision would be sharply focussed.
What is the depth of field on a microscope?
Depth of field is the depth of the specimen clearly in focus and is greater at lower magnifications.
How do you you notice as you change the diaphragm openings?
As you change the diaphragm openings (aperture), the depth of field will be affected. A larger aperture (small f-stop number) will result in a shallower depth of field, meaning only a small portion of the image will be in focus. On the other hand, a smaller aperture (large f-stop number) will increase the depth of field, resulting in a larger area of the image being in focus.
Does the depth of field increase or decrease when one moves to a higher magnification on a microscope?
The depth of field decreases.
Is the depth of field on a dissecting microscope less than the depth of field on a compound microscope?
Yes, the depth of field on a dissecting microscope is greater than on a compound microscope. This is because the dissecting microscope has lower magnification, allowing for a wider field of view and greater depth perception.
What is wide depth of field?
The term "wide depth of field" is not used. Depth of field can either be shallow or deep. The definition of depth of field is this: Depth of field is defined as the range of object distances within which objects are imaged with acceptable sharpness. A shallow depth of field would mean that only objects within a small distance in a scene would be focused; everything else would be out-of-focus. For an example, consider many portrait photos; in them the background is blurred while the person is in sharp focus. A deep depth of field would mean that a much larger range of objects at various distances would be in focus. Most landscape photographs are a good example of this.
What happend to the depth of field if magnification increases?
The higher the magnification the lower the depth of field.
What do you notice when you change the diaphragm openings?
Changing the diaphragm openings affects the depth of field in your photographs. A larger diaphragm opening (lower f-stop number) results in a shallower depth of field, which creates a more pronounced background blur. On the other hand, a smaller diaphragm opening (higher f-stop number) increases the depth of field, keeping more of the scene in focus.
What happens to the depth of field as the magnification increases?
As magnification increases, the depth of field decreases. This means that less of the image will be in focus, leading to a narrower range of objects appearing sharp in the photograph.
What happens to depth of field as you increase the diameter of an iris diaphragm?
As the diameter of the iris diaphragm increases, the depth of field decreases. A larger diaphragm lets in more light, leading to a shallower depth of field with less of the image in focus. Conversely, a smaller diaphragm increases depth of field by letting in less light and making more of the image appear sharp.
