Deck Options

Deck options are accessed by selecting a deck on the 'Decks' screen, and then clicking 'Options' at the bottom of the screen.

Anki allows you to share options between different decks, to make updating options in many decks at once easy. To do this, options are grouped into an 'options group'. By default, all newly created decks use the same options group, and decks imported from previous versions of Anki have separate option groups. If you’d like to alter the settings on one deck but not other decks, click the gears icon in the top right and add a new options group.

Please only change options that you fully understand, as inappropriate adjustments may render Anki less effective.

Options are not retroactive. For example, if you change an option that controls the delay after failing a card, cards that you failed prior to changing the option will have the old delay, not the new one.

New Cards

Steps controls the number of learning repetitions, and the delay between them. Please see the learning section for an overview of how the steps work.

Steps over a day (1440 minutes) are supported as well - if you want, you can define a schedule like 10 minutes, 1 day, 3 days and then finally 7 days before the card becomes a review card.

If there’s nothing else to study, Anki will show cards up to 20 minutes early by default. The amount of time to look ahead is configurable in the preferences. One thing to be aware of is that the due counts will differ between the deck screen and study screens in this case. The deck screen will not count cards that are not ready, but the study screen will. This is done so that you can tell which decks need your attention.

Anki treats small steps and steps that cross a day boundary differently. With small steps, the cards are shown as soon as the delay has passed, in preference to other waiting cards like reviews. This is done so that you can answer the card as closely to your requested delay as possible. In contrast, cards that cross a day boundary are scheduled on a per-day basis like reviews are. When you return to study the next day, the per-day learning cards will not be shown first, as that can make the first half of a review session frustratingly difficult. Instead, the cards will be shown after reviews are completed. They are included in the review count rather than the learning count, due to the way they are handled internally.

Order controls whether Anki should add new cards into the deck randomly, or in order. When you change this option, Anki will re-sort the decks using the current option group. One caveat with random order mode: if you review many of your new cards and then add more new cards, the newly added material is statistically more likely to appear than the previously remaining cards. To correct this, you can change the order to ordered mode and back again to force a re-sort.

When you select random order, Anki will randomize your notes, keeping the cards of a given note close together. The cards of a given note are shown in the order their card types appear in, so that siblings are introduced consistently - otherwise you could end up in a state where some notes had all their cards introduced and other notes had only one or two. Please see the "bury related" option below for more info.

New cards/day tells Anki how many new cards you’d like introduced on each day you open the program. Missed days will not cause the cards to pile up. The limit applies to the current deck and subdecks. This means if "French" has a limit of 20 cards and "French::Lesson 1" and "French::Lesson 2" both have limits of 15 cards, you’ll get 15 cards from lesson 1 but only 5 cards from lesson 2.

Studying new cards will temporarily increase the number of reviews you need to do a day, as freshly learnt material needs to be repeated a number of times before the delay between repetitions can increase appreciably. If you are consistently learning 20 new cards a day, you can expect your daily reviews to be roughly about 200 cards/day. You can decrease the reviews required by introducing fewer new cards each day, or by turning off new card display until your review burden decreases. More than one Anki user has excitedly studied hundreds of new cards over their first few days of using the program, and then become overwhelmed by the reviews required.

Graduating interval is the delay between answering 'Good' on a card with no steps left, and seeing the card again.

Easy interval is the delay between answering 'easy' on a learning card and seeing it in review mode for the first time.

Starting ease controls the easiness that cards start out with. It is set when a card graduates from learning for the first time. It defaults to 250%, meaning that once you’ve finished learning a card, answering "Good" on subsequent reviews will increase the delay by approximately 2.5x (eg if the last delay was 10 days, the next delay would be 25 days). Based upon how you rate the card in subsequent reviews, the easiness may increase or decrease from what it starts out as.

Turning off bury related…​ will prevent Anki from burying siblings, and instead Anki will just try to avoid showing siblings directly after one another in the same session. For this to work, your new cards/day setting needs to be large enough for the cards of multiple notes to be included.


Maximum reviews/day allows you to set an upper limit on the number of reviews to show each day. When this limit is reached, Anki will not show any more review cards for the day, even if there are some waiting. If you study consistently, this setting can help to smooth out occasional peaks in due card counts, and can save you from a heart attack when returning to Anki after a week off. When reviews have been hidden due to this option, a message will appear in the congratulations screen, suggesting you consider increasing the limit if you have time.

Easy bonus allows you to set the difference in intervals between answering 'Good' and 'Easy' on a card. For instance, with the default value of 130%, Easy will give an interval that is 1.3 times the Good interval.

Interval modifier allows you to apply a multiplication factor to the intervals Anki generates. At its default of 100% it does nothing; if you set it to 80% for example, intervals will be generated at 80% of their normal size (so a 10 day interval would become 8 days). You can thus use the multiplier to make Anki present cards more or less frequently than it would otherwise, trading study time for retention or vice versa.

For moderately difficult material, the average user should find they remember approximately 90% of mature cards that come up for review. You can find out your own performance by opening the graphs/statistics for a deck and looking at the Answer Buttons graph - mature retention is the correct% on the right side of the graph. If you haven’t been studying long you may not have any mature cards yet. As performance with new cards and younger cards can vary considerably, it’s a good idea to wait until you have a reasonable amount of mature reviews before you start drawing conclusions about your retention rate.

On the SuperMemo website, they suggest that you can find an appropriate multiplier for a desired retention rate. Their formula boils down to:

log(desired retention%) / log(current retention%)

Imagine we have a current retention rate of 85% and we want to increase it to 90%. We’d calculate the modifier as:

log(90%) / log(85%) = 0.65

You can use Google to calculate it for you.

If you plug the resulting 65% into the interval modifier, you should find over time that your retention moves closer to your desired retention.

One important thing to note however is that the tradeoff between time spent studying and retention is not linear: we can see here that to increase our retention by 5 percentage points, we’d have to study 35% more frequently. If the material you are learning is very important then it may be worth the extra effort – that’s something you’ll need to decide for yourself. If you’re simply worried that you’re forgetting too much, you may find investing more time into the initial learning stage and/or making mnemonics gives you more gain for less effort.

One final thing to note is that Anki forces a new interval to be at least 1 day longer than it was previously so that you don’t get stuck reviewing with the same interval forever. If your goal is to repeat a card once a day for multiple days, you can do that by setting more learning mode steps instead of by adjusting this modifier.

Maximum interval allows you to place an upper limit on the time Anki will wait to reshow a card. The default is 100 years; you can decrease this to a smaller number if you’re willing to trade extra study time for higher retention.

Hard interval specifies what the next interval will be when you press the Hard button. The percentage is relative to the previous interval, eg with a default 120%, a card with a 10 day interval will be given 12 days. This option is only available when the experimental scheduler is enabled in the preferences.

Turning off bury related…​ will prevent Anki from burying siblings, and instead Anki will just try to avoid showing siblings directly after one another in the same session.

Review cards are always shown in random order. If you wish to see them in a different order, you can use a filtered deck. More specifically, Anki randomizes reviews by grabbing batches of 50 cards in the order that they exist in the database, randomizing each batch, then putting them together. This means that there is a slight bias towards older cards being shown first, but it prevents individual cards from showing up in a predictable order.


When you forget a review card, it is said to have 'lapsed'. The default behaviour for lapsed reviews is to reset the interval to 1 (ie, make it due tomorrow), and put it in the learning queue for a refresher in 10 minutes. This behaviour can be customized with the options listed below.

If you leave the steps blank, Anki will not place the card back in the learning queue, and it will be rescheduled as a review with its new interval determined by the settings below.

The new interval is determined when you answer "Again" to a review card, not when the card finishes its relearning steps. For this reason, the "Good" and "Easy" buttons during relearning do not alter the interval again - they only control which step you are on. If there is only a single step (the default), the "Easy" button will be hidden, since it would accomplish the same thing as the "Good" button. If you have 2 or more steps, "Easy" is not hidden, to allow you to graduate cards from the queue before all of their steps are finished.

'New interval' controls how much Anki should reduce the previous interval. It reduces the previous interval to the percentage you specify. If a card had a 200 day interval, the default of 0% would reduce the interval to 0 (but see the next option). If you set this option to 50%, the card would have its interval reduced to 100 days instead.

'Minimum interval' allows you to apply a minimum limit to the above option. The default setting says that lapses should be reviewed one day later. The interval must be 1 day or more.

The leech options control the way Anki handles leeches. Please see the leeches section for more information.


Anki monitors how long it takes you to answer each question so that it can show you how long was spent studying each day. The time taken does not influence scheduling. If you take longer than 60 seconds, Anki assumes you have walked away from your computer or have been distracted, and limits the recorded time to 60 seconds, so that you don’t end up with inaccurate statistics. The 'ignore answer times…​' option allows you to adjust the cutoff threshold. The minimum cutoff is 30 seconds.

If 'show answer timer' is checked, Anki will display the current time taken for each card in the study area.

By default, Anki automatically plays audio on the front and back of cards. If you uncheck 'automatically play audio', Anki will not play audio until you press the replay audio key, r or F5.

The 'Always include question side when replaying audio' option controls what happens when you choose to replay audio while the answer is shown. Please note that it does not control what happens when you show the answer; for that please see this section.
