Visualization notes
- Blue areas represent placed parts on the sheet.
- Light background area is unused material (potential scrap).
- Single-part mode uses a rectangular grid; its mixed-orientation alternative is a rough estimate.
- Part outlines, holes, common-line cuts, and irregular shapes are not modeled. Verify production layouts in CAM.

Scrap Management Opportunity
This job generates 10.36 kg of scrap material ($31.09 cost before scrap value).
Record clean remnants by material, thickness, and actual dimensions. Count a remnant as available only when it can be identified, retrieved, and matched to a future job.

Increase Batch Size
LOWYour batch size (50 parts) results in 153 empty positions on the last sheet. Consider ordering in multiples of 203 to maximize utilization.
Improve Scrap Recycling Program
LOWYour scrap value is 17% of material cost. Reviewing scrap handling, sorting, and recycling agreements may improve how much of the waste material cost you recover.

Nesting input worksheet
Use this nesting calculator to estimate sheet and plate yield for a laser quote. Enter one rectangular part size or several part types to view a first-sheet layout, total sheets, batch utilization, scrap weight, and material cost. Carry the material and nesting assumptions into the quote after checking the layout in CAM.Rectangular estimates only; verify with CAM
Plate nesting calculator: estimate parts per plate after kerf, spacing, edge margins, and rotation rules.
Also supports material nesting calculator, sheet nesting calculator, plate nesting calculator, online nesting calculator, and sheet utilization calculator workflows.
Parts per sheet
Fit count after margins, kerf, spacing, and rotation.
Utilization
Part area compared with purchased sheet area.
Waste cost
Unused material value across the estimated sheet count.
Material cost
Batch cost to carry into the laser quote.

Use this result as a quote input, then calculate time, gas, overhead, and margin separately.
Assumption checklist
- Confirm sheet size, part dimensions, kerf, edge margin, spacing, and rotation rules.
- Verify simplified rectangular nesting against CAM output for production quotes.
- Send utilization and material cost to the laser cutting calculator before export.
Sheet Nesting Review Notes
1. Plan around common sheet sizes
Compare the part family against stock sizes your supplier carries before ordering. Use this calculator to see how the material estimate changes with the dimensions you can actually buy.
2. Group similar parts together
Keep each nest to one material and thickness, plus any required grain orientation. Within that compatible batch, add multiple part sizes and set the quantities needed.
3. Track large remnants as inventory
For large, clean remnants, record the material, thickness, and approximate size so they can be reused on a later job when their identity, condition, and dimensions are confirmed.
How sheet utilization is calculated
The result separates physical part area from purchased sheet area so you can estimate batch yield and unused material before building a quote.
Single-part mode uses floor((sheet length − 2 × edge margin) ÷ (part length + kerf + spacing)) × floor((sheet width − 2 × edge margin) ÷ (part width + kerf + spacing)), comparing normal and rotated grids. Mixed mode packs each rectangle with the MaxRects heuristic, counts the returned sheets, and divides total part area by total purchased sheet area.
Mixed mode shows the first packed sheet and totals for the requested batch. MaxRects is a heuristic, not a guarantee of the fewest sheets. Both modes treat each part as a rectangle and omit the actual outline, holes, grain rules, common-line cutting, and CAM toolpaths.
When to Use This Calculator
Use when:
- Quick estimates for rectangular or near-rectangular parts
- Comparing different sheet sizes before ordering material
- Evaluating whether batch sizes justify custom nesting work
- Teaching nesting concepts to new estimators or operators
Not ideal for:
- Complex shapes (circles, brackets, irregular contours)
- Large production nests or true-shape optimization
- Replacing CAM toolpaths or common-line checks
Next step: Use the mixed-part estimate to plan material, then confirm every production layout and cut path in your CAM system.
Important: Simplified Rectangular Nesting
Single-part mode uses a rectangular grid. Mixed-part mode uses a MaxRects packing heuristic and does not guarantee the fewest possible sheets. Both modes treat each part as a rectangle and omit actual outlines, holes, common-line cutting, and CAM toolpaths.
Use this tool for material planning only. Verify production layouts in your nesting software when true-shape geometry, common-line cutting, grain direction, or machine-specific rules matter.
