Mausoleum Capacity Calculator
Crypt count from footprint and configuration.
About this calculator
Planning a mausoleum wing means turning a building footprint into a crypt count, and the arithmetic hinges on how much of that footprint is actually usable once walls and walkways are subtracted. The calculator first strips 1.5 feet of exterior wall thickness from each side of the entered length and width to get the usable interior. It then figures out how many corridor sections fit across the building's width: each section is modeled as two rows of crypts (roughly 7.75 ft deep each, to hold a standard interment plus clearance) flanking a corridor of your chosen width, separated by a 1.25 ft structural wall between sections — so wider corridors or thicker walls directly shrink the number of sections that fit, and thus the crypt count. Along the building's length, crypts are packed side by side using either single-crypt width (about 2.75 ft, matching the roughly 33-inch industry-standard opening) or companion/double-crypt width (about 5.5 ft) depending on which type you select; companion crypts also double the interment capacity per crypt since they hold two sets of remains.
Multiplying crypts-per-level by the number of vertical tiers (typically 2 to 6 in real construction) gives the total crypt count, and total interments accounts for the companion-crypt doubling. A density metric — crypts per 100 square feet of gross floor area — lets you compare efficiency across different footprint or configuration choices. Keep in mind this is a geometric packing estimate using representative industry dimensions, not an architectural or code-compliant layout: real projects still need to account for accessibility clearances, fire egress, HVAC, and local building and cemetery-authority regulations that can reduce the usable count below what raw geometry allows.

How to Use This Calculator
- Enter building length and width in feet, and number of crypt levels high.
- Set corridor width (ft) and select crypt type (single or companion).
- Review Total Crypts, Total Interment Capacity, Crypts per Level, and Crypts per 100 sq ft.
- Use efficiency per 100 sq ft to compare different building configurations.
How the result changes with Building length (ft)
| Building length (ft) | Total crypts | Total interment capacity |
|---|---|---|
| 30 | 72 | 72 |
| 45 | 120 | 120 |
| 90 | 248 | 248 |
| 150 | 424 | 424 |

Frequently Asked Questions
Why does increasing the corridor width reduce the total crypt count so much?
Each corridor section's width is modeled as twice the crypt depth (about 7.75 ft per row) plus the corridor width plus a 1.25 ft structural wall, and the calculator divides the usable building width by that section width to find how many sections fit. Widening the corridor increases that divisor directly, so fewer whole sections fit across the same building width, and each lost section removes two full rows of crypts.
Does adding more crypt levels always multiply the total crypt count proportionally?
Yes — the calculator multiplies crypts per level by Crypt Levels High with no adjustment for structural or code constraints between tiers, so going from 4 levels to 6 levels increases total crypts by exactly 50%. Real construction still caps levels around 6 for practical access and structural reasons, which the calculator only limits via the input's 8-level maximum.
What's the difference between Total Crypts and Total Interment Capacity in the results?
Total Crypts counts physical crypt spaces in the building. Total Interment Capacity multiplies that by how many sets of remains each crypt holds — 1 for single crypts, 2 for companion/double crypts — so an all-companion-crypt design shows the same crypt count as an equivalent single-crypt layout but double the interment capacity.
Does this calculator check building codes, fire egress, or accessibility requirements?
No — it's a pure geometric packing estimate built from representative industry crypt and corridor dimensions, not an architectural or code-compliant design. A real mausoleum layout still needs separate review for ADA-accessible clearances, fire egress paths, HVAC routing, and local cemetery-authority regulations, any of which can reduce the achievable crypt count below what this calculator's geometry suggests.
