Small-ish.

Detergent is dosed for the size of the load and soil level, not for the amount of water.

Your jeans don't bleed, with potential to affect the other items? Are the socks and/or underwear white? I never wash (or dry) jeans with anything else.

Do the whole load together; it doesn't sound like you have enough to separate it out. Save water and combine loads when you can. I've never had jeans bleed; who cares about underwear and socks being affected by color bleed? Turn your jeans inside out to reduce fade.

@Jen K, I wear shorts 85% of the time (not the couple/few months of coastal TX "winter") so my socks are visible. The wash water turns a distinct blue when I wash jeans, which theoretically may be helpful as bluing on whites, but I get better results from bleach on whites, and I surely don't want my shirts and other non-indigo items exposed to blue wash water. Jeans are also a much heavier fabric than other "wear clothes" which isn't conducive for drying together.

Thanks everyone for all the pointers. So I'll use the small or medium line, adjusting up and down (from small and medium) depending on soil level, which will be just the occasional food or soda spill (already got some zout ready for that) and just sweat on the worst days. I had planned on doing them all in one load all together, I didn't even think to take color bleeding into account *facepalm* but all my items have been washed before, so I'd like to think that if the colors were gonna run they would've run by now.

@dadoes I wash jeans with my t-shirts and shorts; I've never had bleeding. I don't dry my jeans in the dryer; I hang them. Perhaps it depends on the type of jeans and if they have spandex or polyester. I don't wear socks that are visible and neither does my husband so it doesn't matter if socks blue; bleaching is hard on the fiber so we never do it. I don't run small loads for one specific item; it's a waste of water. Run bathing towels with jeans to make a load.

I mix loads all the time. I use Shout color grabbing sheets and they work very well. Just thrown in with the clothes. They come in a box that looks like Shout dryer sheets - read the label. Sometimes I’ll use two if I have new clothes that have never been washed or dark denim. and, yes, I’d consider your laid Small or possibly medium.

@Jen K, I don't wash small loads. A load of shirts is typically at least 12, I've had 21 in some instances. Jeans when I'm wearing them is five to seven, Levi or Wrangler. Casual/cargo shorts + underwear is 8 to 10 + 10 to 12 underwear and a couple dark bath towels or hand towels. I have enough whites, socks & towels (use several times) & kitchen linens to go more than a month. Chlorine bleach helps keep washers clean, and I never wash in cold water. Look for my photos of dirty washers I've serviced in discussions about that.

@dadoes Thanks I wrote down your laundry sets in case we need to have this conversation in the future (sarcasm).

That's a fairly small load and you will end up running your electric and water bills high doing that too often. I have to grump at my teens about loads like that.

Oh, and we mix our loads also all the time. If you have new darks, wash them once in warm alone and then your whites will be fine. I can count on one hand the times colors bled in my 50 years. With modern fabrics and dyes, it isn't that much of a problem anymore. Just do a good initial rinse on dark cotton fabrics and you'll be good, especially with those colors grabbers the first couple times you mix them.

Note- about once every year i found up my whites and wash them in hot with either bleach or some oxy cleanser. They will go off even if just from the water. A yearly re-whitening helps

I would consider that load small. 
I would also not go by the lines on the detergent cap as I have found they result in too much detergent. I usually do large loads...I typically have enough laundry to separate by color and by fabric... and I use less detergent than the small load line.

I mix colours in loads all the time, separating them by water temperature rather than colour. The hots all go together, as do the warms. It is very rare that I have anything bleed, and by rare I mean maybe once a year, or less.

Detergent amount is always dependent on load size, water hardness in your area, and amount of soil in the load. Too little detergent will cause dirt and body oils to build up in your clothes and smuts to build up inside of your washer. I tend to error on the side of a little extra detergent because I can always add an extra rinse of needed. With modern HE machines rinses are usually cold water and an extra rinse does not use a lot of additional water so your water bill will not skyrocket.

That sounds like a small load to me.

A large load is usually considered 12lbs, and this Tide link says 11 lbs and the washer 3/4s full.

A medium load is 6 lbs and a washer half full.

The current bottle of Tide Original I have says to use line 1 for medium loads, and when I measure that comes out to 2 tablespoons so for your small load I'd use 1 to 1.5 tablespoons, depending on soil level.

If you do actually want to measure the detergent rather than eyeballing it, I find it easier to do it by weight. Just place the detergent cup on a kitchen scale, tare out the scale and then pour the detergent into the cup until the desired weight.

Thanks again everyone. I'm taking all pointers to heart and still learning. I did the load using the small dosage and all came out great. All stains and odors were gone. I guess I just have to break that mindset of like others think that you have to use the whole bottle every load to get clean lol. I greatly appreciate everyone's input.

Just another thought. I have front load HE machines. For most loads I only use the bare minimum detergent- enough to reach the level marked Minimum on the dispenser. Granted, we generally have just light soil on our clothes.
