Concept illustration only: not the worked plate, actual heat-zone boundaries, a tested load or an approved food-placement arrangement.
The quote says “900 mm griddle”. The menu needs two different items at once. A sketch filled with twenty identical portions looks convincing—until the cook reserves part of the plate for the second item and discovers that the promised layout no longer exists.
Compare the actual food-placement layout and operating task, not appliance width or plate area alone. Separate the external footprint, stated cooking surface, excluded or reserved areas, portion envelopes and control arrangement. A paper fit is a question to test; it is not a meals-per-hour rating.
This guide works through a fictional plate and two layouts. No dimensions below specify a real machine, permitted food spacing or cooking process unless explicitly identified as a manufacturer document example.
Find the cooking surface inside the appliance dimensions
Request the exact offered model's dimensional drawing and plate specification. Overall width and depth include more than food-placement space. Identify the cooking surface, splashback, grease channel or drain opening, controls, projections and the installation footprint separately.
For a real example, Moffat's Waldorf GP8900G technical sheet, revision AN.W8.01.2020, distinguishes a 900 mm appliance width from a stated 892 × 530 mm cooking surface. It also describes separate left and right heat zones and plate options. Those are model-specific statements, not the dimensions or control map of the fictional plate here. Obtain the current document matching the actual offer.
Check whether the proposed surface is smooth, ribbed or a mixture, and which finish is supplied. Moffat's GP8900G-B product page lists optional plate finishes. Do not assume an image of one version establishes the surface or working arrangement included in your quote.
Ask the supplier to identify any areas that cannot be used for the proposed task and the relevant instruction. A channel is not extra cooking space. Equally, do not invent an edge exclusion or claim that a manufacturer's stated surface is uniformly suitable for every food. Keep the documented geometry and your own planning reservations visibly different.
Worked plate: 900 × 600 becomes an 840 × 520 planning rectangle
Fictional paper exercise, not a manufacturer requirement. Imagine a plate outline 900 mm wide and 600 mm deep. For this sketch only, the planner excludes 30 mm at each side and 40 mm at both front and rear. These assumptions stand in for areas the real proposal must identify; they are not recommended operating clearances or measured hot and cold edges.
| Record | Arithmetic | What it establishes |
|---|---|---|
| Plate outline | 900 × 600 = 540,000 mm² | Fictional gross rectangle only |
| Planning width | 900 − 30 − 30 = 840 mm | Width left after assumed side reservations |
| Planning depth | 600 − 40 − 40 = 520 mm | Depth left after assumed front/rear reservations |
| Planning area | 840 × 520 = 436,800 mm² | 103,200 mm² less than the gross rectangle; no output rating |

The planner has retained about 80.9% of the gross rectangular area. That percentage describes this drawing. It is not a utilisation target, a permitted loading percentage or a prediction of heating performance.
Record an irregular exclusion where it actually occurs. Do not subtract its area and treat all remaining square millimetres as one rectangle: a drain interruption or narrow strip can prevent a particular portion arrangement even when the total area looks sufficient.
Compare one-item loading with a mixed-menu layout
Represent item A by a 140 × 100 mm rectangle and item B by a 150 × 120 mm rectangle. These are hypothetical food-placement envelopes, not serving sizes or cooking instructions. For this paper screen, leave 20 mm between adjacent rectangles within each group. That gap is invented for comparison; actual handling, food-process and manufacturer requirements remain to be established.
Layout 1 uses the whole 840 × 520 rectangle for A. Five columns occupy 5 × 140 + 4 × 20 = 780 mm. Four rows occupy 4 × 100 + 3 × 20 = 460 mm. This chosen orientation therefore holds twenty paper rectangles, with 60 mm total width and 60 mm total depth unused by that grid. Six columns or five rows would exceed the respective planning dimension.
Layout 2 reserves 480 × 520 mm for A and 360 × 520 mm for B. A uses three columns and four rows: 460 × 460 mm for twelve rectangles. B uses two columns and three rows: 320 × 400 mm for six rectangles. The mixed plan contains twelve A and six B, not twenty of either item.
The two adjacent reservations fill the planning width: 480 + 360 = 840 mm. No separate divider or gap between the reservations has been allowed. Any required separation between tasks, food types or tools must be established and added; it may change the count. These are menu reservations, not a drawing of independent heat zones.
Scroll the diagram sideways to read every label.
| Plan / item | Reserved rectangle | Occupied grid | Paper count |
|---|---|---|---|
| Layout 1: A only | 840 × 520 mm | 780 × 460 mm; 5 columns × 4 rows | 20 A |
| Layout 2: A reservation | 480 × 520 mm | 460 × 460 mm; 3 columns × 4 rows | 12 A |
| Layout 2: B reservation | 360 × 520 mm | 320 × 400 mm; 2 columns × 3 rows | 6 B |
Scroll the table sideways to see every column.
A different orientation or portion envelope could change the layout. The purpose is to expose the actual menu mix and missing constraints, not solve a maximum-packing puzzle. Measure representative portions and show how the operator reaches, turns and removes them.
A menu reservation does not create an independent heat zone
Ask for the actual control arrangement and the manufacturer's description of the working areas. Establish which tasks need compatible settings and whether the offered model supports the proposed operation. Do not draw a line on the plate and assume temperatures on either side become independent.
Separate controls do not by themselves establish a sharp thermal boundary or uniform recovery under your particular load. The paper rectangles say nothing about temperature distribution, heat transfer, recovery or food outcome. A photograph of evenly browned portions cannot fill those evidence gaps.
Give the supplier the required menu mix and representative operating pattern. Ask what assessment will establish the proposed settings, loading and finishing result. Keep the responsible food-safety personnel involved in the actual process. This article provides no temperature, cooking time or safe contact method.
Check the next batch and the bench around the plate
Twenty paper positions cannot be converted to twenty meals, or multiplied by an invented cycle rate. Different components can arrive and finish at different times. Turning, checking, removal, clearing the surface and reloading may constrain the task before the rectangle is full.
For the mixed plan, record when A and B arrive, how many are required at each pickup, which operations share the cook's attention and where finished items go. Ask the provider to assess the actual sequence with representative loads and the agreed conditions. Retain unsuccessful or untested combinations as open questions.
Draw incoming ingredient space, utensils, clean landing and plating alongside the appliance. Keep the manufacturer's installation requirements separate from the working area your team needs. A wider griddle that removes the only useful landing space may change the whole station's task rather than simply increase production.
If the cooking equipment or duty changes, include the ventilation system brief in the review. A fit on the bench does not establish the suitability of the surrounding installed system.
Prepare a plate-layout brief with the assumptions attached
For your own supplier brief, record gross rectangle, reservations, product envelopes, separate menu layouts and actual operating evidence. Replace the fictional inputs with actual evidence and leave unresolved decisions visible.
Please assess the attached menu layout against the exact plate, supplied finish and control arrangement. Identify documented exclusions, required task separation, handling space and the evidence needed to establish the intended operating result. Do not infer output from nominal area alone.
Discuss the brief through Atlantic Equipment enquiries and compare the griddle range by actual product type and supplied configuration. The useful answer connects the menu, physical layout, controls and installed station.

All worked plate dimensions, reservations, portion envelopes and spacing are fictional. The counts describe selected paper grids only. No food-load recommendation, heat uniformity, recovery time, safe cooking outcome, independent-zone boundary or throughput is established.
About this guide
Prepared by Atlantic Equipment. This guide replaces a nominal-width decision with an explicit menu-layout brief. Its single-item and mixed-item grids show why the plate's available shape, task reservations and actual controls need separate evidence. Use the worksheet to agree what a supplier demonstration must establish before relying on a paper count.
