Start with the exact binding
Rhodia's No18 page describes an A4 staplebound pad with microperforated sheets. The selected orange lined-with-margin maker reference is 18600; Goulet's retail code is RH-18600C. A wirebound pad, a punched pad and a staplebound pad can have related names without identical construction. The broad No18 label therefore needs its binding and ruling option before it becomes a reliable reordering record. This guide uses the staplebound orange version only.
Read the dimension as declared
The maker lists 210 by 297 mm for No18. Goulet uses a rounded inch description alongside that metric format. These are product specifications, not measurements performed by this site. The sources read for this record do not establish a separately measured usable rectangle after a sheet is torn along its perforation. We therefore do not subtract an assumed binding allowance, claim an exact remaining height or use the pad's outer dimension as proof of detached-sheet fit.
Ask the question that matches the task
For handwritten notes kept on the pad, the nominal format and line spacing may be enough to shortlist the product. For a template, scanner feeder, document sleeve or a strict filing system, the detached sheet is the object that matters. Ask the seller whether the stated dimension includes the portion above the perforation, and request the usable sheet dimensions for the current reference. Also confirm whether the proposed process requires an unpunched or punched edge. A similar product photo cannot answer those details.
Retain the answer with the reorder code
If a team approves the pad for a particular form, record RH-18600C and the maker's 18600 reference together, plus the actual condition that was checked. Do not transfer the answer to a black cover, graph ruling or spiral model solely because the series number is the same. Until the detached-sheet dimensions are verified, the site labels that field unknown. The purchase tools can still calculate pad quantities and the known sheet count without pretending to resolve a dimensional question.
Make a supplier question precise
A useful question is: for the current orange lined staplebound maker reference18600, what are the width and height of the sheet below the tear line? Asking only whether the pad is A4 may produce the same nominal catalog answer already available. If the answer arrives, record its date and whether it describes a specification or a measured sample. Keep the original nominal dimension as a separate field. This avoids a later editor replacing one number with another and leaving readers unable to tell whether it describes the pad, the paper before tearing or the detached usable portion.
