How small and how large a part can be — and which of the three limits is the one stopping you.
Every material and gauge we stock, with the smallest blank the bed can hold and the largest one that fits the sheet. Type your part size in and it checks the whole catalog at once, including the secondary-operation limits that are often tighter than the laser itself. Sizes are for the flat blank, which is what has to fit the table — not the folded part.
Inches, unfolded. Orientation does not matter — nesting is free to rotate the part.
The smallest and largest blank we will cut in the material you choose, drawn to scale against each other. Every size here prices instantly — there is no custom-quote tier and no minimum order.
Minimum part size is a property of the machine and does not change with material. Maximum part does — it is the sheet you are cut from, minus a 0.5″ handling margin on every edge, capped by the laser working area. The column tells you which of the two bound the result.
A blank has to clear all three. Which one stops you depends on the material, so the honest answer is never a single number.
A 0.5″ band on each edge is where the sheet is clamped, and where the cut stays clear of the raw mill edge — which is rarely straight or square enough to cut to. That is 1″ off each overall dimension, not half an inch. A 120″ × 48″ sheet yields a 119″ × 47″ blank; a 120″ × 60″ sheet yields 119″ × 59″.
Nothing leaves the table larger than the table. Most of our sheet is 48″ or 60″ wide, so the sheet usually binds first — but the bed is the ceiling that no material can raise.
Below a quarter inch square, a blank drops through the slats of the cutting bed, tips into the scrap, or cannot be picked up without damaging it. There is also a size below which nothing can be held for a secondary operation.
Smaller parts are still possible — they get cut on a tabbed skeleton, held to the surrounding sheet by micro-joints and snapped apart after delivery. That is how a run of tiny brackets or shims actually gets made. See gang sheets and volume pricing.
This catches more people than any other rule here. A formed part unfolds much larger than its folded footprint — a 24″ deep box with 6″ flanges unfolds far wider than 24″. Unfold it in CAD and measure that. Our bend allowance calculator gives you the flat length, and the DFM lookup explains quote codes 3113 and 3114 if one comes back.
The usable area against the sheet it came from, drawn to scale for the material selected below. The band is only half an inch, but it comes off all four sides.
A part can clear the laser and still be the wrong size for what happens next. These are checked against the blank in the card at the top of the page.
Powder coating carries its own size and weight envelope, and it is a hanging line — oversized or heavy parts hit the oven opening or the hook rating rather than a dimension. See powder coating and DFM codes 3331 / 3333. Every operation also has a weight ceiling; the material weight calculator will tell you what a blank weighs before you commit to a gauge.
The questions that come up most about how small and how large a part can be.
0.250″ × 0.250″. Below that a blank drops through the slats of the bed, tips into the scrap, or cannot be picked without damage. Smaller parts are still possible on a tabbed skeleton — held to the surrounding sheet by micro-joints and snapped apart after delivery. That is the normal route for tiny shims and brackets; see gang sheets.120″ × 60″, and the sheet you are cut from minus 0.5″ on every edge. On 120″ × 48″ stock that is 119″ × 47″; on 120″ × 60″ stock it is 119″ × 59″. The table above gives it per gauge and names which limit bound the answer.0.5″ band on each edge is the clamping zone, and it also keeps the cut away from the raw mill edge, which is rarely straight or square enough to cut to. Note it comes off both sides — 1″ off each overall dimension, which is the part people forget.2″ × 2″ — smaller parts shift or flip under brush pressure. A single press-brake bend cannot exceed 120″. Powder coating has its own size and weight envelope because it is a hanging line. All of these are checked against your blank in the section above.96″ × 48″) and the exact sheet is confirmed at order. The status column marks which is which, and the filter above will narrow the table to confirmed sizes only.0.250″ minimum and the 0.5″ per-edge margin are the same values the per-gauge DFM preflight on every material page reports, the 120″ × 60″ working area is from fiber laser and capabilities, the deburring floor is from the deburring guide, and sheet sizes come from the live material catalog. Nothing here is interpolated.
