Font size OCR api

Hello,
I am using the free ocr api and i want to know where i can get the font size from the api ?
Thanks

The height of the bounding box is proportional to the font size.

“Words”: [
{
“WordText”: “Word 1”,
“Left”: 106,
“Top”: 91,
"Height": 9, <== small font
“Width”: 11
},
{
“WordText”: “Word 2”,
“Left”: 121,
“Top”: 90,
"Height": 33, <== larger font
“Width”: 51
}
.
