Why is my MiniMap so small?

I downloaded the JourneyMap Mod for Minecraft but the map is too small or too small. I want that you can see everything on the map, so all blocks.

You just have to explore more

Zoom? Have KP of the mod but tip times on mouse advice or arrow keys or mouse advice + CTRL or CTRL and + or

No just zoom

In some mods you can zoom in on the large view. Most of the time this also works for the small one.

And with the large view, you only see the areas you've already been to. The rest are hidden.

Try zooming with the mouse wheel

Or press the + or - left in the middle.

Run wherever you want to display the blocks on the map. Maybe it works.
