On a small shelf, begin with one focal piece and arrange the others around its full footprint. A few visible faces usually make a clearer display than a crowded row of overlapping accessories. Plan the layout from the position where you actually view it.
Map the shelf you have
Measure the usable width, depth and height. Check the furniture's load guidance before adding figures or risers. Make paper footprints for each product using its maximum assembled dimensions, including anything that extends beyond the base.
Place the largest footprint first. Then test the remaining pieces without forcing every gap to hold another object. Empty space gives you room to handle the figures and makes their silhouettes easier to distinguish.
Choose one organizing idea
A small shelf can be organized around a series, a pair of characters or a shared color. You do not need all three. If the shelf contains several unrelated series, a similar level of visual detail or a simple background can help the arrangement feel intentional.
Choose which character should catch your eye first. Place that piece where its face and main feature remain visible. Smaller pieces can support the composition, but avoid positioning them directly in front of the focal character's expression.
Use height only when it improves the view
A suitable riser can reveal a rear figure, but it also reduces overhead clearance and changes how the base is supported. Check the riser's dimensions and load rating, and keep the complete base supported. Do not balance a statue on an improvised narrow object just to create a second row.
If a second row still hides important details, a single row may be the better layout. Rotating pieces into display over time is another option; every item does not have to be visible at once.
Test from normal distance
Step back to the doorway, then sit or stand in your usual viewing position. Check for faces hidden by hair, weapons crossing neighboring figures and a door that cannot close. Take a quick photo to spot overlaps that are easy to miss while arranging.
Make one change at a time. Remove a piece before buying extra storage solely to solve a crowded layout. When choosing the next addition from the statue collection at Super Saiyan Sphere, decide which position it will occupy before ordering it.
