Why Does My InDesign Label Sheet Fill Down Instead of Across?

Separate the list from its placement on the sheet

Write down the intended record sequence using stable identifiers. Then sketch the sheet's actual positions. A packing team may read across each row, while the merge has been configured to proceed down a column. Both arrangements can contain the same records and still create a practical handoff error.

Adobe documents Rows First and Columns First under Layout Of Records in the Multiple Record Layout tab. This setting controls placement traversal. It does not establish whether the source itself is correctly sorted.

Do not immediately rearrange the source to compensate. A compensating sort can conceal the original layout setting and create a second ordering problem when someone later changes the traversal option.

Preview with an unmistakable six-record fixture

In a copy of the target, use six short, distinct identifiers: A through F. Choose a layout that actually fits two columns and three rows. Keep the target dimensions, margins and spacing unchanged while comparing the two traversal options.

Inspect the Multiple Record Layout preview. With the intended two-column, three-row arrangement, a Rows First sequence is A B on the top row, C D in the middle and E F at the bottom. A Columns First sequence is A D, then B E, then C F when those same source records fill down each column.

These positions depend on the stated grid and starting arrangement. If fewer records fit, the comparison no longer has the assumed geometry. Establish the actual previewed row and column count before interpreting a different pattern as a software error.

Hypothetical packing workflow

A fictional seller packs orders by reading each printed row from left to right. Their source sequence is A, B, C, D, E, F, but the label sheet shows A and D on its top row. The next rows show B E and C F.

That pattern is consistent with the illustrative Columns First arrangement. The designer checks the actual setting, selects Rows First in a copied target and previews the fixture again. Suppose the new top row is A B, followed by C D and E F.

The observation would support matching traversal to this packing method. It would not prove that the order data is correct or that the physical printer feeds sheets in the expected orientation. Those checks still use the actual output and handling process.

Hand over positions that can be checked

Save the accepted source sequence and traversal choice together. Include a small labeled sheet map in the handoff so that the operator can compare the first row and first column before processing a full job.

If downstream equipment reads labels in a different order, agree on the required mapping before changing either control. A barcode or QR code can contain the correct product information while occupying a position the operator associates with another record.

After generating the final file, inspect the identifiers at the start, a row boundary and the last partially filled page. This targets ordering transitions without claiming that a clean first row validates every record.
