Current 13-tier density scale

Estimate density-based freight class using the current 13 density brackets.

Tool-to-Tool Workflow

Connected Freight Workflow

Move from shipment measurements to density, freight class, pallet planning, trailer space, and final review. Where supported, shipment values transfer directly between tools so you do not have to enter the same information again.

1

Measure

Enter dimensions, weight, quantity, and units.

Supports single shipments, identical pieces, mixed items, and different-size groups.

Shipment values transfer automatically 2

Density

Calculate cubic feet, total weight, and density.

Transfer dimensions, weight, cubic feet, and density into the Freight Class Calculator.

3

Freight Class

Estimate class using the current 13-tier density scale.

Review nearby class bands, advanced handling factors, formulas, examples, and result guidance.

Pallet values transfer automatically 4

Pallet Planning

Plan single pallets or mixed pallet groups.

Compare sizes, weights, quantities, stackability, overhang, per-group totals, and overall density.

5

Trailer Space

Calculate linear feet and trailer floor usage.

Compare orientation, stacking, best fit, floor positions, and 28-ft, 48-ft, or 53-ft trailer utilization.

6

Confirm

Review before quoting or booking.

Check class context, handling considerations, and supporting commodity guidance before you finalize the shipment.

Core Freight Planning Tools

Eight Powerful Tools. A Smarter Way to Plan.

Each tool serves a specific freight-planning need, from shipment measurements and trailer space to diesel costs and hazardous-material reference. Connected handoffs reduce repeated data entry where supported.

1

Freight Class Calculator

Calculate freight class for almost any shipment setup.

How We Build the Tools

How Greenspark Builds Freight Tools

Use real shipment inputs

Outside packaged dimensions, weight, quantity, stackability, overhang, and orientation.

Show the math and context

Formulas, nearby class bands, examples, trailer usage, and result explanations.

Keep the workflow connected

Transfer shipment values between calculators so users don’t have to re-enter them.

Built for planning, not blind answers. When packaging, commodity details, carrier rules, or NMFC provisions may affect the result, the tool explains what still needs to be confirmed.

Built by Greenspark.Group

FreightClassCalculator.tools is built and published by Greenspark.Group LLC , a Florida-based company that builds focused web tools for freight, trades, and practical business work.

We built this site for the early stages of freight planning — when you need to check shipment numbers, compare options, and understand the result before opening a broker or carrier portal.

All tools are free of ads and unnecessary distractions, fast on desktop and mobile, and focused on helping you get an answer quickly. The site is updated frequently as we add tools, improve calculations, and connect more of the freight-planning workflow. We put a lot of effort into making each tool easy to use. Important information is shown directly within the calculator, often above the fold, so you do not have to search the site to find it. Tooltips and inline guidance are built into the tools so common questions can be answered without leaving the page.

The goal is simple: help you find what you came for without wasting your time.
