How Many Slabs in Container Calculator - Granite, Marble, Quartz
Slabs in Container Calculator
Welcome to our calculator that helps you estimate the number of slabs, or square meters/ square feet of any granite, marble, quartz or any other stone for that matter that will fit in one container. This is your go-to tool for estimating stone slab weights and also the total weight of stone in a container.
You can estimate for any container size, and even adjust maximum container weight limit.
Whether you handle granite, marble, quartz, or other stones, this calculator simplifies shipping and logistics calculations.
Use our slab number calculator to plan how many slab fit in one container with precision.
Save time and ensure accurate estimates for your next project. Ready to dive in? Try the calculator now and find out exactly how many slabs fit in a container.
What This Tool Does
Our calculator estimates the weight of a single slab and calculates the total number of slabs that can fit in a container.
How the Calculator Works
- Select the maximum allowed weight for a container – some ports allow a maximum of 28,000kgs or 28 tonnes but some ports allow lesser, – check online for maximum allowed weight limits for 20’ft container for your specific port of discharge.
- Select materials like granite, marble, or quartz that you want to calculate for
- Select packaging material and type which could be Wooden crates, pallets or Iron pallets.
- Choose the length, width and thickness of the slabs that you want to order – this way we can calculate the weight of slab and ultimately calculate how many slabs fit in a container
How to Calculate How Many Slabs Fir in a Container?
Input length, width, and thickness in centimeters for precise calculations. The tool uses material density and container weight limits. It includes standard frame packaging weights, for realistic logistics planning. Hence, you get a comprehensive estimate tailored to your shipment needs.

Does This Include Packaging Weight?
Select A-frame or crate packaging for granite, marble, or quartz slabs. The tool adjusts weights automatically for accuracy. Estimate additional packaging to ensure safe transport during shipping.

Skip time-consuming density research. The tool relies on industry-standard data for dependable estimates. Thus, you focus on planning, not calculations.
What This Tool Does Not Do
Select A-frame or crate packaging for granite, marble, or quartz slabs. The tool adjusts weights automatically for accuracy. Estimate additional packaging to ensure safe transport during shipping.
Limitations of This Tool
The tool calculates weights for rectangular slabs only, not irregular shapes. It excludes fragility or palletization factors in estimates. Sometimes, due to larger or smaller size of slabs, more slabs can fit in a container.
What You Should Double Check Manually
- Confirm container weight limits with your shipping provider for accuracy.
- Check material density variations with suppliers, as natural stone differs slightly.
- Get accurate calculations of how many slabs fit in a container from the supplier – along with photos to see the packaging

Frequently Asked Questions
How accurate is this calculator?
It delivers reliable estimates using average density values. Verify with suppliers for precise results, as stone varies.
Can I use this for custom stone types?
No, the tool supports only preloaded materials currently. Custom densities inputs may come in future updates.
Does it support both inches and centimeters?
Yes, input dimensions in multiple units. Thickness requires centimeters for consistent, accurate calculations.
What’s the assumed container limit?
The tool assumes a 20 ft container with a 28,000 kg weight limit, standard for stone shipping; however, you can change this based on your port of discharge.
Can I export or save results?
Not yet. Screenshot results for records until we add export features in future updates.
Pros & Cons of the Calculator

Advantages of Using the Tool
Estimate slab weights, number of slabs that fit in a container and container loads in seconds.
Include packaging weights for precise shipping plans.
Save time and boost efficiency with automated calculations.
Things to Keep in Mind
The tool handles rectangular slabs only, not irregular shapes. It doesn’t support multi-container calculations yet. Estimates rely on average density, so verify specifics with suppliers.
We recommend manual checks for critical shipments to ensure accuracy.
Accuracy Disclaimer
Important Accuracy Notes
The calculator uses average density values, not field measurements. Natural stone density varies slightly by batch. Container limits assume standard 20 ft containers with a 28,000 kg capacity. Confirm actual weights with suppliers for critical shipments. We advise using these slab number estimates as a starting point.
Cross-check with official documents, suppliers and authorities before finalizing logistics plans.
Additional Features
Upcoming Features
Look forward to irregular shape calculations in future updates. Multi-container support and exportable results are planned. Custom stone density inputs may be added soon. Petros Stones aims to enhance the tool’s functionality for all users.
