Thread To Needle Sizing

[Anne Bonnys Locker]

Hi folks,

I've been going through my thread references as the numbering system most used on here doesn't align with what I normally use. My threads are all high tenacity polyester and measured in metric ticket so I have been confused when I see things like #69 to #277. As I am probably not the only on I thought this might help others.

A thread number like #69 is actually a ticket size for stranded nylon and the equivalent in the polyester is 40 TKT. To confuse matters further the Indians and Asians refer to this as 210/d3 or 210/3 or 2103 which can also be called 630 as it is 3 strands of 210 weight. Confused yet?

This simple table might help:

Needle Polyester Nylon

Size Ticket Ticket

100/110 40 69

120 30 92-99

140 16 138

160/180 12 207

200 277

230 277-346

250 415

Of course these are only approximate as depending on what you are doing it is possible to use a slightly smaller or larger needle if the thread moves through it readily.

Do these numbers tally with what others have found in the real world?

Your needle/thread chart matches my personal experience. I have bought thread on eBay that comes in the cord/size and in T designations. I use charts I found online to cross reference these numbers with the sizes I am familiar with.

The most common difference is nylon thread is between the B or V numbers and the T numbers. For instance, B or V, or # 69 is the same as T70, while #277 equals T270, which is the same as 4 cord linen.

Confused yet?
