The six-measure fit card
Scroll horizontally to see every column.
| Measure | How to capture it | Why it matters |
|---|---|---|
| Portion length | Longest recurring food package | Sets minimum internal length |
| Portion height | Highest point after bagging | Curved lids can reduce usable corners |
| Pouch mouth | Flat open edge | Must fit the active seal zone |
| Clean seal zone | Unfilled, wrinkle-free pouch above food | Protects seal consistency |
| Chamber envelope | Usable L × W × profile, not exterior case | Determines physical acceptance |
| Counter envelope | Machine plus open lid and service access | Determines whether it will actually be used |

Build a zero-cost paper chamber
Tape paper or cardboard to the manufacturer’s published chamber length and width. Mark the seal bar and any clamp position. If the lid is curved, note the published maximum depth as a best-case center measurement, not a promise that the entire rectangle has that height.
Set a real, bagged portion on the template. Smooth the pouch mouth across the seal line. If the package only fits diagonally, check that the entire mouth still crosses the active seal bar without a fold.
- Repeat with your widest and tallest normal portions, not a one-off holiday item.
- Photograph the template with a ruler so your shortlist remains comparable.
- Add a margin for placement error; a theoretical edge-to-edge fit is fragile in daily use.

Plan for the lid, ventilation, weight, and service
A closed exterior dimension does not show the working envelope. Measure the lid at full opening, nearby cabinets, the path to the outlet, and the space needed to clean the chamber. For an oil-pump machine, consult the exact manual for level placement, oil access, transport, and ventilation requirements.
If the machine must be moved for every use, compare its weight with your actual storage route. A smaller chamber that stays ready can be more useful than a larger one that never leaves a low cabinet.

Resolve dimensions on one evidence sheet
Product pages can mix exterior width, chamber width, seal-bar length, maximum depth, and pouch size. Those measures are not interchangeable. Copy each value with its exact label and source URL, then mark any dimension the manufacturer does not publish. A missing lid profile or usable corner height remains an uncertainty; do not silently replace it with the chamber’s maximum center depth.
Normalize units on a separate calculation line while preserving the manufacturer’s original value and wording. Do not round a near-fit dimension upward or treat a drawing’s outer case line as usable chamber space. Record the document revision or access date, because a retailer listing and a current model manual can describe different revisions. If two official sources disagree, keep both values visible and ask the manufacturer which applies to the exact model code.
Use the paper template only to eliminate obvious mismatches. A template cannot reproduce a curved lid, clamp, seal-bar hardware, or the way a filled pouch settles under vacuum. Mark a candidate ‘fit unresolved’ until the open-lid clearance and the recurring filled package have been measured together or confirmed by model-specific documentation.

| Evidence field | Record | Release rule |
|---|---|---|
| Exterior case | Closed L × W × H | Counter planning only |
| Usable chamber | Internal L × W × stated profile | Package-fit evidence |
| Active seal zone | Published usable width | Pouch-mouth limit |
| Open-lid envelope | Measured or explicitly published clearance | Unknown until verified if absent |
