There is no standard.
However, having said that, if you buy a map book or sheet, there are various scales which are generally used:
1:221,760 (1 inch = 3½ miles)
1:63,360 (1 inch = 1 mile - no longer issued by OS)
1:50,000 (2 cm = 1 km - the OS Landranger series, replacing the 1:63,360 series)
1:25,000 (4 cm = 1 km - the OS Pathfinder series)
The scale chosen depends upon the use.
The smaller the scale (the second number above) the more detail that can be put on the map.
The first example scale above is a map book for driving and generally shows major roads and some minor roads to allow for route planning.
The second/third examples can be used for driving, cycling or walking as they show roads, bridal ways, footpaths
The last example is good for walking as it shows more detail including field boundaries.
Maps with even smaller second numbers are used by specialist surveyors, eg to show property boundaries.
Atlases have a much larger second number.
The larger the second number, the less details that can be put (accurately) on the map.
There is no standard scale of a map. The scale used depends on what the map is used for. A motorist may use a 4 miles to 1 inch, a cyclist 1 mile to 1 inch (or 1:50 000), and a walker use 1:25 000 - and so on.

It is drawn to full size
A map scale shows the ratio between the distances on the map and the distances in reality (one inch= 10 miles, for example) whereas the map legend tells what the various symbols on the map represent (landforms, size of roadway, state capitals, etc.)
Where does the series number on a map appear
A map scale of 1:175,000 means that 1 centimetre on the map represents 175,000 centimetres on the ground.
There is no standard scale of a map. The scale used depends on what the map is used for. A motorist may use a 4 miles to 1 inch, a cyclist 1 mile to 1 inch (or 1:50 000), and a walker use 1:25 000 - and so on.
The scale of a world map refers to the ratio between the size of objects on the map and their actual size on Earth. It is typically presented as a ratio or a graphic scale bar. This helps users understand the level of detail and accuracy portrayed on the map.
The size of an area on a map compared to its actual size is known as the scale of the map. Scale is typically represented as a ratio or a graphic scale, indicating how much the map has been reduced from the real world. For example, a scale of 1:10,000 means that one unit on the map represents 10,000 of the same units in the actual world.
This is a large-scale map. Maps with scales of 1:75,000 and larger are used for tactical, administrative, and logistical planning. These are the maps that a soldier is most likely to encounter. The standard large-scale map is 1:50,000; however, many areas have been mapped at a scale of 1:25,000.
I just call it a map. Scale is the size of the map relative to the reality. If you draw a map of your bedroom that is the same size as your bedroom, it has a scale of 1:1. I use a map of my town that is 1:100,000 (one centimetre equals one kilometre).

scale of the map. The scale of a map can be represented as a ratio, such as 1:10,000, indicating how much the distances on the map are reduced from the actual distances on the earth's surface.
The relationship between the size of an area on a map and its actual size is represented by the map scale. The scale provides a ratio or a fraction that shows how much smaller the map is compared to the actual area being represented. It helps users understand the distance and size relationships between locations on the map and in reality.
A 1:50,000 scale map represents a much larger area than a 1:1 scale map. To determine the size in real life, you would need to know the dimensions of the map itself.
