When a Cut Vinyl line item shows a much larger vinyl quantity than expected, CoreBridge is usually calculating material from the finished (trim) size, the quantity, and how those pieces fit on the stock (roll) width in Layout Manager. This article explains how to read those values so you can see why the Bill of Materials (BOM) quantity is what it is.

How material usage is calculated
Layout Manager drives the material quantity that appears on the BOM. Usage updates from:
- Finished / trim width and height
- Total quantity
- Stock (parent roll) width and how pieces nest on that width
In simple terms, CoreBridge multiplies the finished size by quantity, then lays that out on the roll width to determine print area, waste, and total material area. Accurate roll width on the material is important for correct results.
Cut Style Letter and quantity
On cut vinyl assemblies that use Cut Style: Letter, the character count for the text often becomes the component quantity (for example, 18 characters → quantity 18). If Layout Manager still uses a finished size as wide as the full phrase for each of those quantity units, material area is multiplied by that character count. That is a common reason a BOM shows a large square-footage number for what looks like one set of letters.
Example: Finished/trim size 108" × 6" and quantity 18:
- Area per unit = (108 × 6) ÷ 144 = 4.5 sq ft
- Total material ≈ 4.5 × 18 = 81 sq ft
If the stock width is narrower than the finished width (for example stock 54" with finished 108"), Layout Manager splits each unit across panels on the roll. Waste can still show 0% when panels fill the stock width cleanly.
How to review Layout Manager
1. Open the Estimate or Order and select the cut vinyl line item.
2. Open the Components tab for the cut vinyl component.
3. Under perimeter cutting / plotter settings, click Edit Layout to open Layout Manager.
4. Review Stock Size, Trim Size / Finished Size, Print Area, Material Total Area, and Waste.
5. Compare those values to the vinyl material quantity on the Bill of Materials for the same line item.
What to check when vinyl looks high
- Confirm Cut Style (Letter vs other styles) and whether quantity matches the character count.
- Confirm letter Height and the resulting finished/trim size in Layout Manager.
- Confirm stock (roll) width on the selected vinyl material matches the roll you cut on.
- Confirm whether you intended one phrase layout or one piece per character—quantity × finished size is what drives square footage.
