OSRS UI Scaling: RuneLite Blur & Sidebar Size

ClientsRuneLite and official client

UpdatedNov 8, 2026

Which client are you on?

RuneLite and the official Jagex client have separate desktop controls. Mobile uses separate interface controls. For tablet play, see whether RuneLite can run on a tablet and OSRS tablet setup for PvM. The OSRS setup hub covers gear and setup beyond scaling.

Layout and client size

Fixed or resizable: which OSRS layout should I use?

Fixed starts with a 765×503 game area before stretching. Resizable fills the window and offers classic or modern panel positions. Choose the layout that keeps both the game view and controls comfortable to reach.

Fixed and resizable OSRS layouts
Feature	Fixed - Classic layout	Resizable - Classic layout	Resizable - Modern layout
Game area	765×503 before stretching	Fills the window	Fills the window
Side panels	Right side, inside the frame	Right side, classic block	Attached to the bottom; stacks into two rows on narrow windows
Chat	Bottom left, fixed	Bottom left; can be transparent or click-through	Same as Resizable - Classic
Make it bigger in RuneLite	Stretched Mode stretches the whole 765×503 frame (“stretched fixed”)	Stretched Mode > Resizable scaling	Stretched Mode > Resizable scaling
Official client Interface scaling	Not available; resizable only	Available	Available

How do I change the OSRS client size?

In RuneLite, drag a window edge to resize the client. To set its startup dimensions, open Configuration (wrench) > RuneLite > Window settings > Game size. The default is 765×503. Turn on Lock window size to prevent accidental resizing.

To choose a layout, open Settings (wrench) > All Settings > Interfaces > General > Game client layout. Fixed - Classic layout uses a 765×503 game area. Resizable - Classic layout fills the window with classic side panels; Resizable - Modern layout fills it with side panels along the bottom.

RuneLite scaling, blur and sidebar

How do I change UI scaling in RuneLite?

RuneLite uses the Stretched Mode plugin to enlarge the game interface; core settings have no single UI scale control. Open Configuration (wrench), search for “Stretched Mode,” and enable it. The plugin is off by default.

In a resizable layout, increase Resizable scaling from its 50% default to make the interface bigger. In a fixed layout, Stretched Mode stretches the game view. Keep aspect ratio and Integer scaling are off by default.

Why does RuneLite look blurry after scaling?

Stretching the game interface can soften edges. Try Integer scaling in Stretched Mode or choose another setting under Configuration (wrench) > GPU > UI scaling mode. Modes include Nearest Neighbor, Bilinear, Bicubic (Mitchell), Bicubic (Catmull-Rom), xBR, and Hybrid (the default).

Increased performance mode in Stretched Mode uses a faster, cruder filter and is ignored when GPU is on. For Windows scaling issues, check the launcher Scale setting next.

Use the RuneLite launcher's Scale field. On Windows, open RuneLite (configure) from the Start menu. On macOS or Linux, run the launcher with --configure. On macOS, use /Applications/RuneLite.app/Contents/MacOS/RuneLite --configure.

This setting changes Java UI scaling. Check the game view as well as RuneLite panels after applying it. The setting also applies when you launch RuneLite from the Jagex Launcher.

Oracle documents Java 2D scaling in 2× steps on Linux X11 and Retina macOS. On Wayland, use --configure to set Scale and check the result on your system rather than assuming the same scaling behavior.

Official client, PvM and monitor setups

How do I make the OSRS interface bigger in the official client?

First switch to a resizable layout. In the official client, open Settings (wrench) > All Settings > Interfaces > General > Interface scaling.

After the March 25, 2026 update, Interface scaling is a dropdown. On desktop, right-click it and select Input to type a value. Use the reset interface scaling button to restore the default.

Does a bigger client hurt PvM?

Fitts's law describes how pointing time depends on target size and distance. A full-screen resizable client can spread the inventory, prayer book, and game view farther apart. Scaling the interface makes targets bigger, but can also increase the distance between them. Which layout feels easier depends on the player.

Players disagree: some prefer a fixed or smaller client for shorter mouse paths, while others use a resizable layout with a larger interface and hidden chat. The fixed versus resizable discussion and players' layout preferences are anecdotes, not a PvM rule.

To reduce mouse travel, map F-keys to side panels under Settings > Controls > Keybinds; this OSRS F-key setup guide covers PvM binds. Inventory Tags can make switches easier to spot, and Menu Entry Swapper can change left-click defaults.

Mouse DPI is personal calibration. Player reports range from 400 to 1600 DPI in this discussion; use the sensitivity that feels controlled with your client size.

What's the best setup for 1080p, 1440p, 4K and ultrawide?

Compare monitor shapes and OSRS client layouts in the monitor simulator.

Stretched fixed with Integer scaling

The fixed game area is 765×503. Integer scaling uses whole-number multiples:

1080p: 2× = 1530×1006 leaves 74 px of screen height for window borders and desktop controls; check whether it fits your available area.
1440p: 2× = 1530×1006 fits comfortably; 3× = 2295×1509 does not fit.
4K: 4× = 3060×2012 fits; 3× = 2295×1509 leaves room for a guide window.

Window borders, the taskbar, and the RuneLite sidebar need extra space, so check the available game area before choosing a size. With Integer scaling off, Stretched Mode can use fractional scaling but may look soft; try another GPU UI scaling mode if it does.

Resizable layouts

1080p, 24-inch: Try Stretched Mode if text is small; leave it off if the interface is already readable.
1440p, 27-inch: Try Resizable - Classic layout or Resizable - Modern layout with Stretched Mode on. Adjust Resizable scaling above or below its 50% default until inventory icons are clear.
4K: You may need Stretched Mode for the game interface and launcher Scale for RuneLite panels. The official client has its own Interface scaling dropdown.
Ultrawide: A full-width window pushes the side panels farther from the middle of the game view. A narrower client window is one option. See the RuneScape 3 ultrawide scaling guide and WoW ultrawide setup guide for related layout ideas.

On a compact screen, compare the OSRS Steam Deck setup and RuneLite Chromebook setup.

Starting points by activity

PvM and gear switching: Try a smaller or fixed-style client, F-key panels, and Inventory Tags. Raise the interface only as much as needed to read it.
Skilling or AFK: Try resizable with a larger interface if you prefer it; mouse distance may matter less for these activities.
Multiple clients: By game area, 2×2 fixed 765×503 clients fit 1080p, 3×2 fit 1440p, and 5×4 fit 4K before window borders and sidebars. Check the available area on your display. RuneLite's Low Detail plugin reduces memory use; it can remove some textures. For tablet windows, see the guide to OSRS tablet split screen.

Keep the current monitor if your OSRS layout fits

Place the RuneLite window or tiled clients on your current screen at its native resolution. Check the real game area, side panels, and text before deciding you need another display. The multi-client monitor layout guide compares OSRS window arrangements; the Gigabyte M32U 4K versus LG 34WQ73A-B comparison covers that specific screen-shape choice.

Optional: check mounting and video connections

Check the monitor and desk before adding an arm.

Look up the monitor's weight without its stand, VESA pattern, and rear clearance.
Match the arm's minimum and maximum load, reach, and tilt to the monitor and its position over the desk.
Check the desk material and thickness against the arm's clamp or grommet limits.

Check the full video path before replacing a cable.

Match the computer's video port to the monitor input, including any adapter or dock. Check that every link supports the resolution and refresh rate you want; some adapters and cables work in one direction only.

A USB-C port's 100W charging rating does not establish video support. DisplayPort over USB-C needs Alternate Mode; power, data, and video are separate capabilities.

What this preview does and does not model

UI scale is illustrative (0.75×); it is not an exact RuneLite plugin setting.
Geometry uses 3440×1440 native pixels with 40px reserved for the taskbar.
panel geometry distance is a straight-line screen-coordinate estimate on a curved-panel approximation, not mouse travel, eye movement, or an ergonomic result.
Window borders, client chrome, and minimum usable client sizes are not modeled.
GPU UI Scaling choice is included in the checklist; this schematic illustrates texture treatment only; it is not an actual GPU or RuneLite shader.
LCD has no OLED pixel-wear mechanism; image retention is not impossible in every condition.

Screen details and tradeoffs

LG UltraWide 34WQ73A-B

3440×1440 workspace for clients and reference material.
Built-in KVM and USB-C support a shared work/play desk.
HDR10 and IPS are manufacturer-listed panel features.

Tradeoff: A 21:9 panel gives less vertical space than 4K.

Try client placement and UI scaling before replacing hardware

The game region is 3440×1400 native pixels, or 3440×1400 logical pixels at 100% desktop scaling. Adjust the real interface in RuneLite; this preview does not measure text clarity or reproduce the plugin renderer.

Try this arrangement on your current monitor before buying. If the interfaces remain readable and all required windows fit, a new screen may not be necessary.
Check the monitor connection, supported refresh rate, desk space and the real client at the intended resolution before choosing hardware.

Apply this layout on Windows

Use the Microsoft FancyZones instructions alongside this plan. On other systems, use your window manager and the copied coordinates.

On Windows: Settings > System > Display. Select the intended monitor, set its native resolution and 100% scale.
In PowerToys FancyZones, open the layout editor on that monitor. Create a custom Canvas layout and use the coordinates below as a placement reference. Native coordinates divided by 1.00 give approximate logical coordinates; confirm the editor’s units. Keep 40px native height clear at the bottom.
Hold Shift while dragging a window into a zone. Check borders, taskbar position and client text; adjust zones in the editor. This tool does not install or overwrite any desktop configuration.

1. In RuneLite enable Stretched Mode and adjust Resizable scaling in your actual client; the preview percentage is illustrative.
2. Use stretched window placement. In RuneLite GPU, choose UI Scaling mode: xBR; 117HD has its own settings.

FAQ

Why doesn't Interface scaling show up in RuneLite?

Interface scaling is an official-client setting. In RuneLite, use the Stretched Mode plugin to enlarge the game interface.

Why is the Interface scaling option greyed out or missing?

In the official client, Interface scaling only works in a resizable layout. Set Game client layout to Resizable - Classic layout or Resizable - Modern layout, then check All Settings > Interfaces > General.

What does Resizable scaling do in Stretched Mode?

Resizable scaling controls how Stretched Mode sizes the game interface in resizable layouts. Its default is 50%; a higher setting makes the interface bigger. Adjust it until text and icons are clear in your window.

Does ::uiquality change the UI size?

::uiquality does not change the UI size. It changes the official client's scaling algorithm: 0 selects Nearest-Neighbour, 1 selects Linear, and 2 selects Bicubic.
