Arrange a display shelf for different model heights
Arrange shelf groups around sightlines, access and the actual load limits before using risers to change model heights.

A shelf display needs clear views and safe access. Check the shelf and support system's load guidance before adding models or risers. Include covers, bases and any display hardware in the load. A decorative arrangement should not depend on assumptions about a shelf's strength or on unapproved changes to its fixings.
Place paper footprints on the shelf first. Leave enough room to lift each model by its base without brushing neighbouring details. Tall objects at the back can work, but only if they remain accessible and do not require reaching over a fragile foreground scene.
Use height differences to create groups rather than a rigid staircase. A tall lighthouse, a lower harbour and a quiet gap can form a readable cluster. Avoid lining every roof or tower up at the same apparent height; their silhouettes may merge into a continuous band.
Test the view from the room
Look from the positions where people will normally see the shelf. A riser that improves the standing view may hide a model from a seated position. Use temporary solid blocks to test heights before choosing a permanent riser. Any final support should be stable, appropriately rated and broad enough for the complete base.
Keep the background and lighting simple. Reflections from covers can obscure a model even when its physical position is good. Shift the model or light before adding more brightness. Leave ventilation and electrical clearances required by any lighting equipment, and follow its installation instructions.
Group models through a shared theme, colour relationship or project sequence. The group does not need identical bases, but a few consistent spacing decisions can prevent it looking accidental. Let one object act as the main subject and give the others room to support it.
Rehearse removal of the tallest and widest pieces. If a cover cannot lift clear or a base must tilt past a delicate branch, adjust the arrangement. Keep the shelf edge clear enough to provide a reliable grip. Photograph the final layout and record where removable parts are stored. A display that is easy to maintain is more likely to remain clean and intact than one whose ideal composition can only be achieved by touching several fragile models every time one is moved.
