[GIS] “Lock” Labels at specific size

arcgis-desktoparcmaplabelinglayouts

I use ArcMap 10.5 and i have created a map with a layer with polygon-features. Each polygon has got its own name. I need all the labels to be shown in the Layout view. So far so good. My Problem is that some of the polygons are very small and some are big. It would be ideal if the labels adjust automatically to the size of the polygon and if that´s not possible i would like to "lock" the labels at a small size so that i can zoom in on them in an exported PDF-file. In the default-mode the label adjust to the zooming but if i zoom out some of the labels disappear.

How do I show all the labels in the finished map?

Set the labels up as you want them to display in the main map.
Convert the labels to annotation (first image below).
Select the option for in the current map and all features (second image below).
The reference scale is the scale that the labels will display the way you set them up (circled in the second image below).
If you zoom in from this scale, the labels will get larger. If you zoom out from this scale, the labels will get smaller.
If you need to change the reference scale: Data Frame Properties > Annotation Groups > Reference Scale.

An updated way to do this (at least in 2.6.0 Brighton) is to:

Go to Layer Properties>Labels>Rendering and check the box that says "Show all labels for this layer (including colliding labels)"

Anyone who sees this in the future, with Leaflet 1.0.0 and higher, you can simply bind the tooltip to the polygon itself, and the "center" direction will actually center it much better than trying to center on a marker would.

My final code looked like this:

sceneLayer.eachLayer(function(layer) {
  var fontSize = layer.feature.properties.area / map.getZoom() * 30000;
  if(fontSize > 1) {
    layer.bindTooltip("<span style='font-size: " + fontSize + "px'>" + layer.feature.properties.name + "</span>", {
      className: "label",
      permanent: true,
      direction: "center"
    }).openTooltip();
   }
});

The fontSize calculation will vary from person to person, and if you simply want a fixed size, that works too, but this automatically attempts to adjust the font size based on zoom level.
