The Art of Knotting and Splicing, Cyrus Lawrence Day, Naval Institute Press, 1947, 1955, 1970, reprinted 1972, third edition, ISBN 0-87021-083-1, LC card # 55-10028, pages 130-136, describes several types and variations of seizings, accompanied by very clear photographs that are keyed to the text.

In those photos, the seizing line is consistently portrayed across 20 separate photos at one fourth the diameter of the line(s) being seized. In addition, the seizing line is shown to be laid up rope rather than twisted rope yarn or twine.


The Handbook of Knots, Des Pawson, DK Publishing, 1998, ISBN 0-7894-2395-2, pages 152-154, illustrates two approaches to seizing and includes two close up images of finished seizings on braided line. By measurement, the 'whipping twine' used to make the seizings is 1/11 to 1/12 the diameter of the seized line.
Small stuff (Naut.), spun yarn, marline, and the smallest kinds of rope. --R. H. Dana, Jr. Source
small stuff any light rope used on shipboard
marline a small usually tarred line of 2 strands
rope a strong line
seizing small stuff that is used for lashing two or more ropes together
spun yarn (nautical) small stuff consisting of a lightweight rope made of several rope yarns loosely wound together

Small cordage is usually known on shipboard as small stuff. It is designated either by the number of threads that it contains, such as "12-thread stuff," "15-thread stuff"; or as "ratline stuff," "seizing stuff," or "marline." Source

Jeffers, Dover Publications, 2003, ISBN 0-486-42989-X (paperback), page 66, which indicates that bigger ropes are seized with bigger Small Stuff.

Line 1 3/4 inches (44.5 mm) or less in circumference is called SMALL STUFF, and size is usually designated by the number of threads (or yarns) that make up each strand. You may find 6- to 24-thread small stuff, but the most common sizes are 9- to 21-thread (fig. 4-3). You may hear some small stuff designated by name without reference to size. One such type is MARLINE-a tarred, two-strand, left-laid hemp. Marline is the small stuff you used the most for seizing. When you need something stronger than marline, use a tarred, three-strand, left-laid hemp, called HOUSELINE. Source
Marline: A double threaded, left handed tarred cord, made from a good grade of American hemp. In general use on shipboard for purposes similar to other small stuff; A tarred hemp, two-stranded, left-handed, small stuff, about 1/8 inch in diameter, used for neat seizings and fine service. Untarred marline is used for making sennit. Source
