Thank you Hans again for another guest post.
Non-Standard Standard Formats
The title seems contradictory, but this is about formats that are not of a common standard height and width, but instead combine height and width of different standards.
One common example is the HBxWA5 format, I think the notation was introduced by Ashford. This format combines the height of the "Bible" (Personal) format and the width of the A5 format, hence the name "HB" x "WA5".
Some time ago, I found two ring binders that were advertised as "Business Card Holder". Unfortunately, they are marked as unavailable in the meantime.
Below is a size comparison between standard size and the respective wider format. I used claspless models of the same height and similar ring size for better comparison.
Top left is a Bible size claspless model with 20mm rings, bottom left is the ring binder with 1" rings, same height, but about A4 width: HBxWA4.
Top right is an A5 size claspless model with 30mm rings, bottom right is the ring binder with 1" rings, same height, but about A4 width: HA5xWA4.
Below is the Bible-Height model "OF402" opened.
Height: 202mm, width: 256mm, thickness ~45mm, fully opened width: 535mm.
2" center distance "Personal" rings of 1" diameter, 165mm between the buttons.
Left: Clear pocket insert, height: 179mm, width: 215mm; 30 included. Double-sided two columns, three rows pockets.
Right: Sample sheet, height: 171mm, width: 210mm.
Below is the A5-Height model "OF392" opened.
Height: 262mm, width: 256mm, thickness ~45mm, fully opened width: 535mm.
2¾" center distance standard A5 rings of 1" diameter, 212mm between the buttons.
Left: Clear pocket insert, height: 240mm, width: 215mm; 25 included. Double-sided two columns, four rows pockets.
Right: Sample sheet, height: 210mm, width: 210mm.
Please note that the provided clear sheets exceed the design height of the respecitve mechanic. But the sheets have the inner corners cut in a concave shape, to allow access to the push-buttons of the mechanics.
Both ringbinders are of the same finish: Outside is a dark soft padded PU leather with a nice natural structure. Inside an orange-beige PU leather with a super-fine irregular dimpled structure. A full-height shallow pocket at the front cover, a simple pen loop towards the top of the backcover.
As mentioned in the introduction, both are marked unavailable in the meantime. I haven't been able to find any other supplier for such formats.
Feel free to ask, if you have any questions.
Do you know of other non-standard ring binders combining different standard width and height?

Thank you Hans for another guest post.
Interesting!
ReplyDeleteI would add Personal Wide and Pocket Plus to the list!! Personal Wide is nearly B6 which is a far more sensible size to use!
ReplyDeleteI think that there is no "standard" for Personal Wide? It seems that it is something unspecified between Personal width and B5 width, mostly 120-130mm.
DeleteThe original design height of Personal is 6¾", equal to 171.45mm. If you want keep the common squareroot-2 ratio, you get 121.23mm.
I did not hear about Pocket Plus. It looks like formats up to 128x90mm are used, but that would be JIS-B7.
The original Pocket height was 4¾", equal to 120.65mm. The Pocket width of 81mm could be expressen as 3.3/16" in imperial dimensions, leading to a ratio of 1.5.
Most of the height, width and aspect ratios are somewhat strange...
