    I got a new set of arrows for Christmas, the same type that I shoot now. I went to my local archery store to have a new rest and sight out on, and asked them to cut my new arrows to 28". However, when I got home today and compared them to my old arrows, they were longer. Turns out he cut them to 29" instead of 28" like I asked, and the inserts are already glued in.
    So will this length difference make a huge difference in how the arrow travels? basically, if my sight is set up for a 28" arrow at 25 yards, is my longer arrow going to shoot at the same spot?

    No, just have them re-cut. He should do them free for the mistake. You want them the right length.

    They will most likely not hit in the same spot. There are a lot of variable in arrows. Length is one of them, arrow weight is another. What is your draw length?

    My draw length is 29". I'm pretty new to all of this, will he be able to take the insert out to cut the arrows?

    Lets get all the info, 29" draw length. What's your draw weight and what arrows and what spine are they? What rest is on your bow?

    Draw weight is 65 pounds. I'm using carbon express whitetail 350 spine. I just had them put on a QAD ultrarest hunter.

    Just put new inserts back in. Again, he should do this for his mistake.

    It will work just fine, but you will most likely need to re-sight in your sight to match. I shoot an arrow that is about an inch longer than what most people use with a QAD Ultrarest and they work just fine.

    Do you know what your total arrow weight is including your broadhead, insert, arrow, fletchigs and nock?

    At 65 pounds, using a 100 grain point, the difference between 28 and 29 inches tips the chart between 400 and 340.

    I referred to an Easton/Beman chart because that's what I have handy. CX should be very similar if not the same.

    Bottom line is that impact point with field points won't be significantly different due to the weight difference from one inch of length. However, you may or may not have problems with broad head tuning due to a slight dynamic spine difference.

    According to the Carbon express site, 28" - 31" at 65lbs would use 350's, so at 29, he's should be just right.

    Info from a Carbon Express chart is good info to have.

    Based on this, if it were me, I wouldn't worry about the difference and use them as is. Try them out and not fix something unless it's broken.

    You might find that you like the 29 inch length better.

    You can always make it shorter.

    Awesome thanks for all your help guys! I think I'm going to leave them as they are for now and see how they shoot compared to my 28" arrows and hopefully I won't need to make any adjustments. I just like to have everything consistent so having two different arrow sizes worries me some.

    You will get a little more weight and the spine will be a little more limber. The drop probably won't be noticeable 40 yards and in but beyond that you might see a little difference in drop. Nothing substantial but I would want them all to match. Ask him to cut and put in new inserts.

    Besides the weight affecting speed, how does arrow length affect left/right?

    I personally would leave them as is for now. Just adjust your site as it will probably be a tad low due to the arrow being a few grains heavier. I have a 27 inch DL and when i got my new bow I left my arrows a tad longer at 28.5 as i had the same thing happen to me. I personally like them being a little longer now for the broadhead clearance and the little extra weight to the arrow.

    I wouldn't think an inch would make a huge difference but having your arrows cut to the proper length is important i used to shoot very long arrows far to long for my draw length and once i got them cut they were much more accurate.
