Resizable Minimap

A lightweight, client-side BepInEx mod for Valheim that lets you scale the on-screen HUD minimap to whatever size suits your display. It only changes how the minimap is drawn — it does not alter gameplay, world state, or any server data, so it is safe to use on both single-player and multiplayer servers.

GUID: com.oldschooldeveloper.resizableminimap
Version: 0.1.1
Author: oldschooldeveloper
Type: Client-side, visual-only

Features

Resize the HUD minimap anywhere from 75% up to 250% of its default size.
Adjust the size live, in the field, without opening any menu — just hold Alt and tap an arrow key.
Your chosen size is saved automatically to the BepInEx config and restored on the next launch.
Purely visual and client-side: no gameplay or multiplayer side effects.

Controls

Hold Left Alt or Right Alt and press an arrow key, anywhere on screen:

Input	Effect
Alt + Up Arrow	Make the minimap larger
Alt + Down Arrow	Make the minimap smaller

The shortcut works regardless of where your cursor is, because Valheim locks the pointer during gameplay. Each step changes the scale by 5%, and the value is clamped between 75% and 250%.

Configuration

The mod writes to BepInEx/config/com.oldschooldeveloper.resizableminimap.cfg.

Setting	Section	Default	Range	Description
`Scale`	`Minimap`	`1.0`	`0.75 – 2.5`	Visual size of the HUD minimap. Changes apply immediately.
`Alt + Arrows Resize`	`Minimap`	`true`	`true` / `false`	Enables or disables the Alt + arrow-key resize shortcut.

You can change these two ways:

In game — via the shortcut above, or with ConfigurationManager (press F1 if installed).
Out of game — by editing the .cfg file directly; the HUD updates live when the game starts.

Requirements

BepInEx 5 for Valheim.
Harmony (bundled with BepInEx 5).

Installation

Install BepInEx 5 in your Valheim folder.
Copy ResizableMinimap.dll into Valheim/BepInEx/plugins.
Launch Valheim — the config file is created on first run.
Hold Alt + Up/Down arrow to set your preferred minimap size.

Building from source

The project targets .NET Framework 4.7.2 and detects a common Steam installation (or E:\SteamLibrary) automatically. For a different install, set the Valheim paths before building:

$env:VALHEIM_MANAGED_DIR = 'C:\Program Files (x86)\Steam\steamapps\common\Valheim\valheim_Data\Managed'
$env:BEPINEX_CORE_DIR    = 'C:\Program Files (x86)\Steam\steamapps\common\Valheim\BepInEx\core'
dotnet build .\ResizableMinimap\ResizableMinimap.csproj

Then copy ResizableMinimap/bin/Debug/net472/ResizableMinimap.dll to Valheim/BepInEx/plugins.
