Full-size card
The aboriginal "full-size" PCI agenda is authentic as a acme of 107 mm (4.2 inches) and a abyss of 312 mm (12.283 inches). The acme includes the bend agenda connector. However, a lot of avant-garde PCI cards are half-length or abate (see below) and abounding avant-garde PCs cannot fit a full-size card.
Card backplate
In accession to these ambit the concrete admeasurement and area of a card's backplate are aswell standardized. The backplate is the allotment that fastens to the agenda cage to balance the agenda and aswell contains alien connectors, so it usually attaches in a window so it is attainable from alfresco the computer case. The backplate is anchored to the cage by a 6-32 screw.
The agenda itself can be a abate size, but the backplate accept to still be full-size and appropriately amid so that the agenda fits in any accepted PCI slot.
Half-length addendum agenda (de-facto standard)
This is in actuality the applied accepted now – the majority of avant-garde PCI cards fit central this length.
Width: 0.6 inches (15.24 mm)
Depth: 6.9 inches (175.26 mm)
Height: 4.2 inches (106.68 mm)
Low-profile (half-height) card
The PCI alignment has authentic a accepted for "low-profile" cards, which basically fit in the afterward ranges:
Height: 1.42 inches (36.07 mm) to 2.536 inches (64.41 mm)
Depth: 4.721 inches (119.91 mm) to 6.6 inches (167.64 mm)
The bracket is aswell bargain in height, to a accepted 3.118 inches (79.2 mm). The abate bracket will not fit a accepted PC case, but will fit in a 2U rack-mount case. Abounding manufacturers accumulation both types of bracket (brackets are about busted to the agenda so alteration them is not difficult).
These cards may be accepted by added names such as "slim".

MiniPCI and MiniPCI Express cards in comparison
Mini PCI was added to PCI adaptation 2.2 for use in laptops; it uses a 32-bit, 33 MHz bus with powered admission (3.3 V only; 5 V is bound to 100 mA) and abutment for bus arrive and DMA. The accepted admeasurement for Mini PCI cards is about a division of their full-sized counterparts. As there is no admission to the agenda from alfresco the case, clashing desktop PCI cards with brackets accustomed connectors, there are limitations on the functions they may perform.
Many Mini PCI accessories were developed such as Wi-Fi, Fast Ethernet, Bluetooth, modems (often Winmodems), complete cards, cryptographic accelerators, SCSI, IDE–ATA, SATA controllers and aggregate cards. Mini PCI cards can be acclimated with approved PCI-equipped hardware, application Mini PCI-to-PCI converters. Mini PCI has been abolished by the abundant narrower PCI Express Mini Card.
Technical data of Mini PCI
Mini PCI cards accept a 2 W best ability consumption, which banned the functionality that can be implemented in this anatomy factor. They aswell are appropriate to abutment the CLKRUN# PCI arresting acclimated to alpha and stop the PCI alarm for ability administration purposes.
There are three agenda anatomy factors: Blazon I, Blazon II, and Blazon III cards. The agenda adapter acclimated for anniversary blazon include: Blazon I and II use a 100-pin stacking connector, while Blazon III uses a 124-pin bend connector, i.e. the adapter for Types I and II differs from that for Blazon III, area the adapter is on the bend of a card, like with a SO-DIMM. The added 24 pins accommodate the added signals appropriate to avenue I/O aback through the arrangement adapter (audio, AC-Link, LAN, phone-line interface). Blazon II cards accept RJ11 and RJ45 army connectors. These cards accept to be amid at the bend of the computer or advancing base so that the RJ11 and RJ45 ports can be army for alien access.

The PC/104-Plus and PCI-104 anchored anatomy factors cover a stacking 120 pin PCI connector.
Other concrete variations
Typically customer systems specify "N × PCI slots" after allegorical absolute ambit of the amplitude available. In some small-form-factor systems, this may not be acceptable to acquiesce even "half-length" PCI cards to fit. Despite this limitation, these systems are still advantageous because abounding avant-garde PCI cards are appreciably abate than half-length.
