350 standard LPs
At 0.35 cm each, the records use about 122.5 cm of linear shelf space. A 15% growth allowance raises that to 140.9 cm.
Know what fits before you move the collection.
Turn shelf measurements into a practical capacity estimate for records, discs, or books—and leave room for what you’ll collect next.

A workable fit
Your shelf is deep and tall enough, with room for the planned growth.
Measure once. Trust the estimate.
The presets are practical starting points, not universal dimensions. Collections vary.
- Use the clear inside width.
Measure between uprights, hinges, or shelf pins—not the outside width of the furniture.
- Measure a representative stack.
Line up 20 typical items, measure the stack without squeezing, then divide by 20. This catches gatefolds, booklets, slipcovers, and box sets.
- Leave handling room.
A 5% packing allowance makes it easier to pull an item without crushing sleeves or scraping cases.
- Check weight separately.
Capacity here is based on space. Vinyl and books get heavy; always follow the shelf maker’s load limit and add centre support on long spans.
Worked examples
See the assumptions, then replace them with your own measurements.
120 Blu-rays
At 1.25 cm each, the cases use about 150 cm. With 10% growth, plan for 165 cm.
