Decoration is measured... to surfaces over 600 wide only to surfaces over 300 girth only in both not exceeding 300 and exceeding 300 wide items only in m

The statement appears to relate to how decoration measurements are taken for various types of surfaces, but the context isn't fully clear. It seems to specify conditions based on width and girth. Here's a breakdown of the likely meanings:

1. Surfaces Over 600 Wide: This implies that if a surface has a width greater than 600 (presumably in millimeters or another unit), decoration measurements will be applied specifically for that dimension.

2. Surfaces Over 300 Girth: This refers to circumstances where the girth (the total distance around an object) exceeds 300. In this context, measurements are taken based on this criterion.

3. Both Not Exceeding 300 and Exceeding 300 Wide Items: This segment suggests there are conditions under which both narrow (not exceeding 300) and wide items (exceeding 300) are measured. It indicates the need for a clear distinction between the two in terms of decoration application.

4. Only in m: This final part suggests that all measurements are given in meters, standardizing the units for clarity.

If you could provide more specific details or clarify the context of your question, it will help in offering a more precise and tailored response.
