Kaladesh is a large set with 101 commons, 80 uncommons, 53 rares, 15 mythic rares, three variations of each standard basic land, and 30 masterpieces. Not counting the masterpieces, this is the normal size for a large set of this era. Foil cards are included in booster packs with advertised odds of 1 : 67 cards. Masterpieces have advestised odds of 1 : 2160 cards. The set was printed in English in the USA and Belgium.
Kaladesh was sold in 15 card booster packs (which contain an additional ad card). Booster boxes have 36 packs.
The US printing uses sequential collation with C1/C2 common collation.
Packs are back-facing and have 10 commons followed by 3 uncommons, a rare, a basic land, and an ad card. If there is a foil card, it will appear after the rare, displacing a common. (This includes masterpieces.)
|10 Commons||3 Uncommons||1 Rare||1 Land||1 Ad Card|
|9 Commons||3 Uncommons||1 Rare||1 Foil||1 Land||1 Ad Card|
Packs are evenly split between C1 commons and C2 commons. C1 packs have 2-3 A cards, 2 B, and 4-5 C. C2 packs have 4 A cards, 2 or 4 B, and 2 or 4 C.
When a foil appears in a pack, it will displace a common card. Common foils displace A commons and only appear in C1 packs. Uncommon foils displace B commons. Rare foils displace C2 commons. Masterpieces displace C1 commons.
As normal, uncommons are split into equal A and B runs with one or two A cards followed by one or two B cards appearing in each pack.
The A common run consists of 33 different cards each appearing twice. The cards are alternating white, blue, and red. The choice of first card is mostly arbitrary.
The B common run consists of 22 different cards each appearing three times. The cards are alternating black and green. The choice of first card is mostly arbitrary.
The C1 common run consists of 27 different cards each appearing twice plus Eager Construct, the short-printed common. It cards of all colors and colorless cards. The choice of first card is mostly arbitrary.
The C2 common run consists of 18 different cards each appearing three times plus Eager Construct, the short-printed common. It cards of all colors and colorless cards. The choice of first card is mostly arbitrary.
The A uncommon run consists of 40 different cards each appearing three times. The choice of first card is mostly arbitrary.
The B uncommon run also consists of 40 different cards each appearing three times. The choice of first card is mostly arbitrary.
Most of the marketing cards in Kaladesh have a token or emblem on the front face. In addition, there is a card that has an advertisement for Magic Duels on the front face. (The front has an ESRB rating and the back has PEGI, so I'm not aware of any region differences.) They are printed on an 11 × 11 sheet with different items appearing different numbers of times. The choice of first card is mostly arbitrary.
There are two versions of the Kaladesh marketing card sheet. Earlier printings mistakenly did not include the Energy Reserve card.  First, I will give the earlier version. (In a few places, I cross-referenced between the sheets to fill in missing data, but I am fairly confident of correctness.)
|Chandra, Torch of Defiance Emblem × 2||Dovin Baan Emblem × 2||Nissa, Vital Force Emblem × 2|
|Beast × 3||Construct × 5||Construct × 5|
|Thopter × 8||Thopter × 8||Thopter × 8|
|Magic Duels Ad Card × 12||Servo × 22||Servo × 22|
|Servo × 22|
The later version of the sheet is the same in places where the Energy Reserve card was not added.
|Beast × 2||Chandra, Torch of Defiance Emblem × 2||Dovin Baan Emblem × 2|
|Nissa, Vital Force Emblem × 2||Construct × 4||Construct × 4|
|Thopter × 5||Thopter × 5||Thopter × 5|
|Magic Duels Ad Card × 12||Servo × 16||Servo × 16|
|Servo × 16||Energy Reserve × 30|
There is a picture of the foil common sheet available.  Each common card and each basic land variation appear once. The extra Mountain cards at the end are presumed to be fillers.
There is a picture of the foil uncommon sheet available.  Each uncommon card appears once. The extra copies of Refurbish are presumed to be fillers.
There is a picture of the foil rare sheet available.  Each rare card appears twice, and each mythic rare card appears once.
 Here is an official announcement by Wizards of the Coast that Energy Reserve cards were initially missing.
 A picture of the foil US common sheet is available from Desert Bus 2016.
