Start with the cabinet opening
Measure the usable interior width, depth and height. Hinges, a center stile and the door's opening can make the access narrower than the interior. Check that the assembled riser can pass through the opening and stand with all its feet supported. Do not plan to balance it over a step or an uneven shelf.
Measure the lower compartment
Use the clearance beneath the riser's platform rather than its overall height. Place the intended cups or dishes together and measure their tallest point. Include space to take an item out without scraping or lifting the entire riser. A stack that fits exactly may be inconvenient to remove.
Check what fits above
Subtract the riser's overall height from the cabinet's clear height, then compare that remainder with the stack you want above it. Leave a handling margin that works for your reach. If the shelf above adjusts, confirm its installation positions and support requirements instead of assuming any height is possible.
Verify loading and stacking rules
Use the selected model's load limits and instructions for stacking or joining units. A photograph of multiple risers is not enough to establish how many your configuration permits. Keep the support points on a level surface and do not add extra weight merely because there is unused volume.
Try the daily sequence
Open the cabinet and simulate removing the dishes in the order you use them. If retrieving a mug means removing a plate stack, rethink the arrangement. The extra shelf is useful when it improves access, not simply when it increases the number of objects that can be packed into the cabinet.
