All OS maps are criss-crossed by vertical and horizontal grid lines (coloured blue on OS Explorer maps) which are 4cm apart on 1:25,000 scale maps and 2cm apart on the 1:50,000 scale. A grid reference uses six figures to identify a particular spot on a map that is 100 metres square.
Q. Which is bigger 15000 or 1 25000 scale?
The smaller the ratio of the scale, the smaller the ground-area covered, so the map should show that area in greater detail; a map at 1:25,000 will cover a quarter of the area covered by the same size map at 1:50,000, but should show it in more detail.

Q. What does a 1 50000 map mean?
The scale on a map is the ratio between real life sizes and how many times it has been shrunk to fit it on the map. On a 1:50,000 scale map, 1 cm on the map represents 50,000 cm on the ground (= 500 m or 0.5 km).
Q. What does 1 100000 mean on a map?
Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground. For example, a 1:100000 scale map is considered a larger scale than a 1:250000 scale map.
Q. How many miles are represented by 1 inch on the map?
0.4 miles
Q. How many miles is 2 inches on a map?
Map Scale Equivalents
| Map Scale | Miles to Inches |
|---|---|
| 1:100,000 | 1.6 miles = 1 inch |
| 1:126,700 | 2 miles = 1 inch |
| 1:150,000 | 2.4 miles = 1 inch |
| 1:200,000 | 3 miles = 1 inch |
Q. What size is a 1 50000 scale map?
Copyright Ordnance Survey 2017. Maths (still sorry): A 1:50,000 scale means that each millimetre on your map represents 50,000 millimetres or 50 metres on the ground. (Therefore 2 mm on the map represents 100 metres and 2 cm a kilometre).
Q. What size is a 1 10000 scale map?
Large Is Small A map scale might be given in a drawing (a graphic scale), but it usually is given as a fraction or a ratio-1/10,000 or 1:10,000. These “representative fraction” scales mean that one unit of measurement on the map 1 inch or 1 centimeter represents 10,000 of the same units on the ground.
Q. What is largest scale map?
A large scale map is where the RF is relatively large. A 1:1200 map is therefore larger scale than a 1:1,000,000 map….1. Types of Map Scales.
| Size of Scale | Representative Franction (RF) |
|---|---|
| Medium Scale | 1:1,000,000 to 1:25,000 |
| Small Scale | 1:1,000,000 or smaller |
Q. What is largest scale OS map?
The main scales used by Ordnance Survey (OS) for surveying are 1:1250, 1:2500 and 1:10 000. These are referred to as large scale maps, which is when features in the real world are portrayed larger on the map. OS also produce a number of mapping products at other scales, such as 1:25 000 scale and 1:50 000 scale.
Q. What scale are military maps?
A military city map is a topographic map (usually at 1:12,550 scale, sometimes up to 1:5,000), showing the details of a city.
Q. What is the smallest scale map?
A ‘small’ scale map is one in which a given part of the Earth is represented by a small area on the map. Small scale maps generally show less detail than large scale maps, but cover large parts of the Earth. For example, a 1:10,000-scale map is said to have a larger scale than a 1:100,000-scale map.
