Practical tools for dimensional checks, all in one place.
IDCalcs brings together practical tools for dimensional checks, material estimates, production planning, and everyday design reference so you can spend less time searching and more time designing.
Free, fast, and built to be bookmarked.
Core calculators
Sheet metal gauge
Convert gauge to thickness, estimate weight per square foot, and compare steel, stainless, and aluminum. Each metal uses a different gauge standard, and the chart makes that explicit.
Bend allowance
Calculate bend allowance, bend deduction, setback, and flat pattern length from thickness, bend angle, inside radius, and K-factor, with a visual reference and the formulas shown.
Box fit and clearance
Start from product dimensions, add clearance presets for foam, corrugate, or bags, choose a board caliper, and get internal and external carton dimensions with volume.
Unit converter
Inches, millimeters, points, ounces, grams, cubic volume, and board caliper in one place, tuned to the units designers actually bounce between.
Pallet utilization
Cases per layer, layers per pallet, and cube efficiency against standard pallet footprints, with club store height and weight references built in.
Material yield
Estimate how many parts fit on a sheet or roll using trim, bleed, grain direction, or minimum spacing constraints. Costing before the estimate comes back.
Packaging and retail wing
Corrugate strength reference
ECT and Mullen burst side by side, flute profiles A through F with calipers and typical uses, and a McKee-based stacking strength estimate.
Carton dimensioning
Internal to external conversions by flute caliper, plus dimensional weight for the major parcel carriers so shipping cost surprises show up early.
Club store display checker
Half-pallet and full-pallet display envelopes, weight limits, and shroud clearances by retailer, so a display concept can be sanity-checked before rendering.
