Using the standard rules for encumbrance and the character sheet set to use encumbrance 

Why doesn’t being over your characters carrying capacity (over carrying capacity  flagged on sheet) reduce the speed on the sheet to 5 feet?

This is why:

Push, Drag, or Lift. You can push, drag, or lift a weight in pounds up to twice your carrying capacity (or 30 times your Strength score). While pushing or dragging weight in excess of your carrying capacity, your speed drops to 5 feet.

The speed drop to 5 feet only applies when pushing/dragging weight above your carrying capacity (but less than twice your carrying capacity, since otherwise you can't budge it at all.)

Okay then, why isn’t the movement zero?

Quote from Stavros_Araatan >>

Okay then, why isn’t the movement zero?

 because you're not pushing or dragging your inventory.

So are you saying that even when over your carrying capacity you still have a movement of 30 feet

Carrying Capacity. Your carrying capacity is your Strength score multiplied by 15. This is the weight (in pounds) that you can carry, which is high enough that most characters don’t usually have to worry about it.

Since in the PHB it does not say what happens if you carry more then 15 times your Strength score, it is up to the DM if they want to put restrictions on the character.

The variant encumbrance rules give more of the restrictions you may be looking for:

Variant: Encumbrance

The rules for lifting and carrying are intentionally simple. Here is a variant if you are looking for more detailed rules for determining how a character is hindered by the weight of equipment. When you use this variant, ignore the Strength column of the Armor table in chapter 5.

If you carry weight in excess of 5 times your Strength score, you are encumbered, which means your speed drops by 10 feet.

If you carry weight in excess of 10 times your Strength score, up to your maximum carrying capacity, you are instead heavily encumbered, which means your speed drops by 20 feet and you have disadvantage on ability checks, attack rolls, and saving throws that use Strength, Dexterity, or Constitution.

I understand the variant rule, it’s not part of my question

The standard rule is broken into three parts of the sub-heading in chapter 7, lifting and carrying

Carrying capacity : 15x strength 

Push, drag or lift : While pushing or dragging weight in excess of your carrying capacity, your speed drops to 5 feet.

Size & strength (not relevant to the question)

Carrying capacity sets the maximum you can carry but is silent on what happens when you go over weight. Part 2 - push, drag or lift, is specific about what you can do when you go over weight

therefore the potential movement when over capacity, by standard rules, is 5 feet

so by standard encumbrance rules why doesn’t dndbeyond character sheet set the possible movement to 5 feet

As those above have stated the 5 feet is when you are pushing or pulling not carrying.  So you only look at the first of carrying capacity for items and equipment carried.

Max you can carry is 15x strength score.  They do not have RAW on what happens after you go over that limit.  It is DM Fiat at that point and since they do not discuss in carrying capacity of a speed reduction or any other restriction for going over 15x strength score in carrying there is no coding for DDB to modify.

Each of those rules are separate rules for different situations.  They may use a derived stat of one to give you new rules for a different situation but the restrictions on one do not apply to a different rule.

It is up to the DM on what restriction you may have if you are carrying more then 15 x strength score.

I disagree

The basic rules have the three parts clearly grouped in the one section in lifting and carrying and are not separated rules for different situations. 

A character wearing a full backpack, weighty armor, a weapon or two and trying to drag  two sacks full of stuff, is over capacity at str10 and their movement is 5ft.

you might interpret the basic rules as there is no rule to interpret, but they are clearly grouped (see WoTC pdf) and intended to be read together.

but it looks like that’s my opinion. I think you have it wrong and I am asking dndbeyond to correct the code

there's nothing to correct. As written with standard rules, there is no consequence for carrying more equipment in your inventory than your strength score grants you.

Lifting and Carrying

Your Strength score determines the amount of weight you can bear. The following terms define what you can lift or carry.

Carrying Capacity. Your carrying capacity is your Strength score multiplied by 15. This is the weight (in pounds) that you can carry, which is high enough that most characters don’t usually have to worry about it.

Push, Drag, or Lift. You can push, drag, or lift a weight in pounds up to twice your carrying capacity (or 30 times your Strength score). While pushing or dragging weight in excess of your carrying capacity, your speed drops to 5 feet.

Size and Strength. Larger creatures can bear more weight, whereas Tiny creatures can carry less. For each size category above Medium, double the creature’s carrying capacity and the amount it can push, drag, or lift. For a Tiny creature, halve these weights.

This is the standard rules. there's NO consequences for carrying more than you are supposed to be able to, as written. It's IMPLIED you straight up cannot carry more than this, but nothing hard written.

So standard, as you keep insisting, there is nothing to correct.


Variant Encumbrance rules, which is where speed reductions come in, falls under the umbrella of "Variant rules that aren't implemented because it is a variant and not the actual rule" and is something that will be added Eventually(TM).
