Pittsburgh Indoor Tennis Court Directory

This is a list of indoor courts in Allegheny county.  It works pretty much like the outdoor court list but does have some additional information about lighting, price, hours, and how 'fast' the courts are.  Double tap the court title to reveal a detail information page for the court 

The notes column carries some encoded data which indicates the lighting, court speed, general cost plus an additional note if needed.  The notes of how what these numbers mean and how they were derived is at the bottom of this web page.  â€‹

The first set of numbers are a measure of how well the courts are lit.  The measurements came from light meter readings from a Weston Master III Model 737 Universal Exposure meter, pictured at the bottom of the page.  The units of measure is related to lumens or pure light intensity availability.  Multiple numbers indicate variable readings from different spots or different conditions. The numbers themselves probably don't tell you much but their relative values can be useful.  Generally 6.5 and above is a decent measurement.  Below that and you'll notice the poor visibility with numbers at or above 9 being good enough to not notice.

​

As a point of reference, the light measure on a cloudy Pittsburgh winter day registers at 25.  None of the indoor courts match that.  By contrast, the light measure of a somewhat sunny Pittsburgh winter day comes in at 100 to 400.  

​

The speed rating was measured by a home grown contraption that used a weight and a spring scale to detect how much force was needed to move a rubber coated 5 lb dumbbell weight.  There's a picture of that right below here to the right.  The higher the number, the slower the court. This method does not work for har-tru (HT) courts so just be aware that they would be pretty slow.

​

Generally a number like 11 (Mellon Bubble) is pretty fast and you'll notice it.  A number more like 13 is average and a 15 is a slow court on the order of an outdoor painted asphalt court.  As a point of reference, the measurement of my hardwood floor at home is about a 9 and I'm pretty sure you don't want to be playing any kind of tennis on a surface that slick.   

​

The dollar amount listed is for non-prime time and assumes that you don't have a membership.   It's obviously not a complete picture how expensive a court is but it is a good indication.  Generally non-prime time is mornings before 1 or 2pm and Saturday or Sunday afternoon.  Those are the times that the clubs have a hard time filling and, therefore, have cheaper pricing.
