Tennis court surfaces

Posted by jkirk on 8 July 2019 in English (English)

According to Wikipedia there are four main tennis surfaces types:

  • Clay courts
  • Grass courts
  • Hard courts
  • Carpet courts

But when looking at the “sport=tennis’ tag the English and German Wiki pages are note very accurate about the tennis court surface types. The English page does not recommend any “surface” values but refers to the Wiki page (which is ok), but the German page talks about “clay”, “asphalt”, “grass” and “sand”.

But when looking at the”surface” key, only “clay”, “decoturf” and “carpet” are connected with tennis.

“DecoTurf” is a special tennis hardcourt product manufactured by an US company. I think we should avoid using “surface=decoturf”.

When checking taginfo of “sport=tennis” you can see more than 96% of them are combined with “leisure=pitch” but only less than 9% have a “surface” tag. Most of them are “clay”, followed by “paved”, “asphalt”, “concrete” and “sand”. (Next to) none of them are tagged with surface “grass” or “carpet” (or even “decoturf” (good!))!

I am not sure yet, how to tag hard courts (I tend to “hardcourt”), but we should only use the following values for “surface”:

  • clay
  • grass
  • hardcourt
  • carpet

I use grass and paved. Not seen a clay court … I have seen concrete and asphalt used as a surface tag for tennis courts in the data base.

Not certain what ‘carpet’ might mean for wikipedia but most people will think of the carpet in homes. I think some think like ‘artificial_turf’ might be more appropriate.

To me hardcourt says the same as paved. I would not use hardcourt.

I’m not sure how after reading wikipedia you decided 4 surface tags are sufficient when the article says the ITF classify into 9 types (with the 9th being “other”).

Surface code Type Description
A Acrylic Textured, pigmented, resin-bound coating
B Artificial clay Synthetic surface with the appearance of clay
C Artificial grass Synthetic surface with the appearance of natural grass
D Asphalt Bitumen-bound aggregate
E Carpet Textile or polymeric material supplied in rolls or sheets of finished product
F Clay Unbound mineral aggregate
G Concrete Cement-bound aggregate
H Grass Natural grass grown from seed
J Other E.g. modular systems (tiles), wood, canvas
