Load balancers now come in small, medium, and large sizes. The larger the load balancer, the more simultaneous connections and requests per second it can manage. Existing load balancers are now considered “small” load balancers and are unaffected by this change.

You can specify the size of a load balancer during its creation using the size field. The available size values are lb-small, lb-medium, or lb-large.

Example request body:

  "name": "example-lb-01",
  "region": "nyc3",
  "size": "lb-small",
  "forwarding_rules": [
      "entry_protocol": "https",
      "entry_port": 444,
      "target_protocol": "https",
      "target_port": 443,
      "tls_passthrough": true
  "health_check": {
    "protocol": "http",
    "port": 80,
    "path": "/",
    "check_interval_seconds": 10,
    "response_timeout_seconds": 5,
    "healthy_threshold": 5,
    "unhealthy_threshold": 3
  "sticky_sessions": {
    "type": "none"

Once you have created a load balancer, you can’t change its size.
