BF % seems strange

ydyms

I'm trying to focus on lifting now that I'm in maintenance so I decided to measure my body fat percentage with one of the online calculators recommended here on mfp. I do have diastasis recti so my stomach is distended, but it's not fat...
My stats: 109 lbs, 5'3". BF %: 23%???? That makes no sense since I'm really thin.
What am I doing wrong?

What you are doing wrong is believing an online calculator.
They vary wildly.
How you look and your measurements are much better metrics.

Tape measure, mirror and progress photos are all you really need.

That sounds right to me... even though I am with more muscles than I was 8 months ago, I still a have a boat load of body fat.. I use a caliper, measurements, photos and the scale, and even though it is a range number for me, mine is up there too at 5'4" and 113.

I call this the skinny fat challenge...lol

I'm 5'3 and about 125...I'm about 23% BF (last time I had it measured, but not with a DEXA scan). I lift heavy, which might explain the almost 20lb weight difference. I think your BF % estimation could be accurate...just b/c you look "thin" doesn't mean that you don't have body fat, and 23% BF is completely normal.

Look at your mirror and feel your skin. Body fat measurement is very difficult and always an estimate. Even water displacement. My husband does tai chi several hours a day (he teaches it) and is built like a rock. But he's got a lot of 'bacon' - very very dense solid fat - under that muscle. No blub on him anywhere though.

Measure. Tape measures help.

Look at those muscles!

Feel good about what you're doing and don't sweat the numbers.

Buy a scale that actually measures BF.

As a 33 year old female that is a lean bf%

Whether it's accurate or not is subject to opinion

You said you have an issue that causes a measurement point to be swollen, which throws off a calculator which will have some level of error anyways. There is also the issue of if you are measuring accurately? Apply a +15/-20% error margin and you are somewhere in the 18.4-26.45% range. What do your eyes tell you? What does a caliper test tell you (which also has errors)? What is the point of the information? How accurate does it have to be? Unless you are competing in a sport, accuracy typically doesn't matter that much, but monitoring change does.

Keep taking measurements and If you measure the same way every week you can monitor change relatively accurately.

Use the online body fat calculator on fat2fitradio. Google em and you will find quite an accurate calculator that takes into account a lot of your measurements to come out with a good result.

Matching yourself to pictures of others is pretty accurate.
E.g, this website

If you are female then 23% sounds ballpark for your height and weight.
