Is data coming from a REST call? Which version of angular? You want to get length from controller or from template? — sabithpocker

fields is an array inside the data, so you could just use length.

var fieldscount = data.fields.length;

EDIT Since you need the count of fields inside the object, you can just use Object.keys,

Object.keys(data.fields[0]).length

DEMO

var data = {
    "label": "Information",
    "fields": [{
      "name": "name",
      "label": "Team Name",
      "type": "string",
      "config": {}
    }]
 }
 console.log(Object.keys(data.fields[0]).length);
