Core capabilities built into DimWeight3PL Studio
Compares actual scale weight against cubic dimensional weight across 139, 166, and 194 divisors, revealing exactly which carton dimensions trigger expensive multi-pound carrier bracket jumps.
Calculates how switching soft goods or non-fragile bundles from a $0.95 3PL corrugated box to a $0.18 poly mailer saves $3.50–$5.20 per shipment in combined material and DIM fees.
Models when to pre-assemble 3-item bundles at your manufacturer for $0.25 versus paying your 3PL $1.30–$1.95 per order in extra item picks and custom marketing insert fees.
Simulates how splitting inventory across 2 regional 3PL nodes drops average shipping zones from Zone 6.8 to Zone 3.9, offsetting inbound split-freight costs within 45 days.
Zero configuration, zero cloud server dependencies, instant execution.
Drop your weekly ShipBob/ShipMonk invoice or enter SKU dimensions, actual weight, items per order, and 3PL pick/box fees.
Drag the DIM divisor slider to see how reducing carton height by 1.5 inches or negotiating a 166 divisor slashes billable weight.
Download a clean fulfillment SOP assigning each SKU to exact mailer/box limits, pre-kit rules, and carrier service levels.

Multiply package Length x Width x Height in inches and divide by the DIM divisor (typically 139 for UPS/FedEx or 166 for USPS), then round up to the next full pound.
If a 1.5 lb product is packed inside a 12x10x6 inch box (720 cubic inches), dividing 720 by 139 equals 5.18 lbs, which carriers round up to a 6 lb billable weight.
Pre-kit your top-selling 2-pack and 3-pack bundles at the factory under a single barcode so your 3PL bills one first-pick fee instead of multiple extra-item picks.
USPS Ground Advantage uses a 166 DIM divisor and exempts packages under 1 cubic foot (1,728 cubic inches) from DIM pricing, saving $2 to $5 on compact parcels.
Trimming a 12x10x6 box down to 12x10x4 cuts volume from 720 to 480 cubic inches, dropping 139-divisor billable weight from 6 lbs to 4 lbs and saving ~$2.40 per order.
Never. All dimensional weight calculations, 3PL pick-pack audits, and CSV exports run 100% locally in your browser RAM with zero cloud uploads.
