When gaming periods from ancients to the horse and musket period many people want to make sure that their cohorts or battalions have the correct frontage when basing figures. When it comes to World War 2 and modern warfare there is not as much information available or what is available is not often used.
This site
http://balagan.info/infantry-unit-frontages-during-ww2 has compiled a lot of data on World War 2 infantry frontages. Tanks could operate on much greater frontages. I don't recall the web location, but I came across one item of information that a Russian tank battalion, about 30 tanks, attacking on a 1km front was considered a dense formation.
There are a number of sources that provide information on post World War 2 formations. Some of them are rather expensive, while others can be found on the internet for free, and some are out of print. Some of the information that I found was actually from computer games that simulated modern warfare. Comparing that information with other sources confirmed that the data used for the computer games matched that data.
The following is a compilation of data that I have obtained from various sources along with a some images from U. S. army tactical manuals. The first two images are platoon formations with the first one possibly being an offensive formation and the second a U. S. defensive position.. The next two are Soviet company and battalion offensive frontages. I have also added a picture of M1 tanks on exercise in a German field. Similar spacing can be seen in photos from the Iraq wars.

Isby & Kamps, Armies of NATO's Central Front states
"...a (West German) brigade would attack on 12,000m frontage - the
principle of being stronger at the decisive point - the Schwerepunkt - still
applies. A Panzer or Panzer Grenadier battalion woud usually have a 4,000m
sector on the offensive, though for a breakthrough operation it would
concentrate on a 1,000-1,500m spearpoint, or 700-1,000m in a Panzergrenadier
battalion was attacking dismounted..."
Regarding the defense, "...The size of the defensive room s varies,
depending on the terrain and mission. Panzer and Panzergrenadier battalions
would usually hold 5,000m frontage, light infantry battalions 4,000m. Battalion
rooms would be 3,000-5,000m deep, those of brigades up to 25km...The Germans
would deploy 80% of their forces forward and the rest in reserve, in cotrast
with the traditional US 'two up, one back' deployment. Companies would fight
together, and battalions would be deployed in defensive positions, often
without a reserve. If required, the battalion reserve would usually be two
platoons but could range from a single platoon to a full company."
