T206 sizes

[Abravefan11]

Here's a scan of my over sized Mattern surrounded by a few others.

Daryl...nice one!

The following is the data a board member named Dave came up with when he measured his T206 collection back in 2004:

Response to Help/Advice
I've measured all my original T206 collection as part of the data I keep on each card. Here is a summary of the sizes. The cards are virtually all Piedmont (4 Old Mills) and I am virtually certain the none were ever trimmed or are reprints.

Total: 524 cards

Nominal width is 1.438
Measured widths

< 1.420 3
1.420 - 1.429 9
1.430 - 1.439 38
1.440 - 1.449 126
1.450 - 1.459 172
1.460 - 1.469 111
1.470 - 1.479 40
1.480 - 1.489 13
1.490 - 1.499 9
> 1.500 3

The smallest is 1.393, Doc White - Chicago - Portrait
The largest is 1.642, Ira Thomas

Nominal heigth is 2.625

Measured heigths
< 2.580 6
2.580 - 2.589 5
2.590 - 2.599 19
2.600 - 2.609 30
2.610 - 2.619 57
2.620 - 2.629 140
2.630 - 2.639 111
2.640 - 2.649 81
2.650 - 2.659 40
2.660 - 2.669 16
2.670 - 2.679 7
2.680 - 2.689 3
2.690 - 2.699 1
2.700 - 2.709 3
2.710 - 2.719 5

The shortest is 2.453, Germany Schaefer - Detroit
The tallest is 2.716, a tie between Nick Maddox and Moose McCormick

What does all this mean? I don't know, other than there is a wide variation, especially on heigth. Cards are much more likely to be large rather than small.

I tried adding width and height, nominal is 4.063. Of 524 cards, only 72 were lower than nominal in this.

By the way, these measurements were made with pecision digital calipers, with resolution to 0.0005, and accuracy to about 0.001. I've tried repeated measurments on the same cards several times; the numbers repeat within 0.001.

Thanks for the great info.. this thread definitely makes me feel more comfortable about my oddly sized red Cobb (Old Mill). I don't have exact measurements, but it's considerably longer and considerably narrower than any of my other T206's, in or out of holders.

I've found some really helpful insights on size variations on this site...

1 question i have:
Is comparing the measurements of the parallel edges a dependable way to spot a trim? for example if the left edge measures exactly 2 5/8", but say the right edge is 1-1.5mm longer, is that a good indication of trimming? this would certainly be the case if a card has a bat-ear. However, is it possible/probable that a factory cut card can have 2 parallel edges of different length?

I have seen some whacky but factory cuts before. Others will know more but I don't count anything out until I can look at it. (and I am not the best person at finding trimming). Certainly most I have seen are parallel though.

Thank you, Leon.

the card you posted, is there an issue with it? I cannot tell the dimensions of the actual card, but from i can measure on screen, the lengths of
left edge = right edge
and
top edge = bottom edge
