Wide-flanged I-beam DIN 1025 - EN 10034, in particular, the size of HEB 100 is used for the various comparison. The profile sizes are at the same calculation factors.

The table is read so that on the left is the profile size (height), for example HEB100.

HEB100 span of 518 cm indicates the profile's deflection ratio 1:1000, when the girder has in the middle of it a concentrated load (point load) of 1 kN (102 kg).  Deflection is then 518 cm/1000 = 0.518 cm

Similarly, HEB320 beam has deflected 1.53 cm, and the span of 1534 cm (15.34 meters). Tension level kN/cm² is in both cases 2.1 -2.2 kN/cm². You are familiar with the other values in the table. Bending formula does not ask the cross-section shape, so any shape can take.

* Profiles cross-sections are in dwg. format. The drawings can be opened with freely available software. These can use to 2-dimensional and 3-dimensional drawings.

The table above can think that way. Your weight is 1 kN, which is 102 kg and you are crossing the river, with a width of 14 meters. You will need a suitable support profile for the crossing. Then you can well imagine that the profile HEB280 is appropriate, as it has tabled span of 14 meters (1394 cm) having 1:1000 deflection ratio. Suitable bridge for walking can certainly bend more, in which case the example illustrates the magnitude of which the more accurate examination starts. Later, all loads are derived from the values ​​in the table, not only to a single profile, but to all profiles and loads.
